Does the change in enviroment cause the organisms that live on a rotting log die or run away?

Yes, if you take something thats adapt to its enviroment and place it in a different enviroment it will die, or try to find a suitable enviroment. This is only with organisms that are weaker then some and cant adapt fast enough. Often the most simple organism is the strongest, without heating and air conditioning humans would have alot of problems with moving, even from the central united states to the southern states. In the past, thousands of people died from a heat wave that swept accross the US, and the tempuratures werent that high, if you are use to the mid/southern states. But it was in the northern states that it happened.

Few complex life forms we know of can survive exposure temperatures that low for more than a moment. However, if pockets of milder temperatures could be found (thermal vents, well isulated hybernation dens, etc) some life would likely adapt. Life forms that could mature and reproduce in one warm season (such as a plant that produces spores capable of surviving such a harsh winter) would have a great advantage. Plants such as trees woudn't stand a chance, as is true of many things humans and other complex life depend on for food and shelter. \n\nAnother consideration would be the erosion due to lack of any plants capable of maintaining a root system to stablize soil. Between the turbidity from erosion and likelyhood that all rivers would freeze solid through most of the winter, most life in rivers and lakes would become extinct. Since the upper temperature is not much if any higher than what we have now, the average temperatue is much lower. This would concentrate vast amounts of water in the icecaps, possibly enough to greatly increase the salinity of the oceans, which would also see a major drop in temperature. Most marine life is more sensitive to temperatue changes than terrestrial or freshwater life, so a great number of extinctions there also.\n\nSo no, life would not survive other than perhaps a few simple life forms. Even a drop of a dozen degrees in average temperature would be devastating in the long run for life as we know it.

1. Global warming of the surface layers of the oceans reduces the upward transport of nutrients. \n\n2. Plankton growth becomes unstable when the supply of nutrients is reduced. \n\n3. This has a negative impact on the food chains of the oceans  - demograghic species shifts occur in fish who are reliant on plankton for nutrition. In turn, fish who feed on THOSE fish are either forced to move to new feeding grounds or are themselves in danger of extinction.\n\n4. This in turn impacts on the marine food chain available to humans, putting strain on resources elsewhere (more reliance on crops and alternative forms of proteins, which may not be asgood for us). Thus gobal warming could store up a future of disease for mankind.\n\n5. Plankton also acts (along with rainforests) as the earth's 'filter' so a reduction in plankton also has an impact on the uptake of the greenhouse gas carbon dioxide into the oceans. Hence more greenhouse gasses are in the atmosphere because there are fewer plankton to absorb them. In addition, the few plankton that are left become saturated.\n\n6. Scientists speculate that eventually global warming will cause the collapse of the plankton ecosystem and, when this happens, all food chains leading up from plankton will be in danger of extinction.

There is no answer to this question.\n\nNot all  living organisms adapt under environemental stress. We can see this simply by looking at widespread organisms like leopards. Despite living everywhere from tropical deserts to rainforest to temperate alpine tundra they remain completely indistinguishable form one another. Although a desert leopard suffers from serious environmental stress in terms of water and prey availability and a mountain leopard suffers from cold and a forest leopard suffers from fungal diseases and so forth the organisms don't adapt at all. It is a generalist species and it remains a generalist with no specific adpations to environmental stress.\n\nWe can even prove experiementally that not all species dapat to environmental stress. Simply grow a perti dish fill of different species of bacteria and let it dry out. As the water stress increases most organisms will either die or become dormant. There is no evidence whatsoever of adaptation over any time scale.\n\nSimilarly not all porganisms will flee. Most will simply die, hibernate or scrape through.\n\n\nWhat a dumb question.

Over the last several decades a significant decline in frog populations all over the world have been noticed, they are just not moving to diffrent locations.  Right now thousands of species are considered endangered or extinct.\n\nFrogs have been on this planet for more the three hundred millions years.  They were around at the time of the dinosaurs and out lived them.  They belong to the class amphibia, meaning double life.  This name fits them because they spend part of their life in the water and part of their life on land.  Unlike reptiles amphibians as a whole rely on water a lot more and can never move far from it.  Today there are almost 5900 species of known amphibians, which 4800 are frog species.  Frogs and toads (which are a type of frog) belong to the order anura.  Of this order there are 29 different families.  Many biologists question why frogs are in a state of decline, an answer with more the one apparent culprit.  It seems to be a combination of problems such as habit destruction, cattle grazing, agriculture, pollution, climate change, UV radiation, pesticides, invasive species, and even road traffic.\n\nHumans have caused much destruction to the natural environment.  We reduce the number of habitats suitable for many species to thrive in, causing them to migrate elsewhere, adapt to us, or die off.  Frogs are very fragile creatures that adapt slowly to major change.  They always must maintain wet, moist skin and due to their dependency on water they are unable to migrate long distances to find suitable habitat.  If we destroy the only pond in an area where will the frogs go?  We forget that they are small animals and a distance of a mile might be too much for them.  \n\nForest fragmentation of a few hundred feet is enough to wipe out an entire population of frogs.  Something as simple as a road can devastate a species’ numbers.  If a road blocks them from their mating ground it can be an impossible task to cross it.  Many times on a warm sunny day the road will get very hot, and the frog’s skin will dry out while crossing it, resulting in its death.    Along with forest fragmentation comes the edge effect.  With the edge effect a once cool shaded area can change dramatically.  The edge effect causes greater changes in temperature and moisture that can be unsuitable for many frog species.   Microhabitats can dry out and temperatures inside the forest fragment can become increasing cold due wind patterns.  Along the edge different vegetation can take over resulting in invasive species of both plant and animal.  In Brazil an Amazonian frog species has shown great decline and forest fragmentation seems to play a key role.  Adult survival was not effected by fragmentation but mean clutch size was reduced by 17%.  By experiments it has been shown that the fragmentation of the forest causes increase predation, increase in interspecific competition, and slower growth rate resulting in delayed reproduction.  \n\nNot just forest fragmentation causes frog decline but also other human alterations to habitats is causing declines worldwide.  Wetlands are the homes of many species of frogs and humans over the years have in some way changed the landscape.  The wetting and drying of the wetlands has great influence on many organisms and frogs are no different.  The Murray-Darling Basin of Australia has been modified for irrigation flow and has reduced the overbank flooding into flood plain wetlands.  This degradation of the wetlands has caused all frog species in the area to decline by an average of 23%.\n\nAgriculture is also another way in which humans alter the habitat.  Both rangeland and cropland reduces the population size of frogs.  Cattle grazing greatly alters the habitat.  First off the habitat many times must be made suited for grazing.  This means frog habitat can be destroyed causing a direct effect or the cattle can interfere with frog migration, causing an indirect effect.  By the grazing of livestock migrat

a decomposer is an organism that derives its nutritition from dead or decaying organic matter.\nA common example would be a mushroom or most fungi
702645
From exactly what you said in bold letters....they break down organic matter.  Otherwise the Earth would be littered with dead animals, leaves, trees, birds etc.  Fungus, bacteria, and insects are all decomposers and a very important part of the Life Cycle.\n\nThe organic matter is then released into the soil and taken up in the raw nutrient/mineral content by plants>animals eat plants>animal dies>cycle repeats.

What is your question?? Dead sea life as in stuff that has been happening for 3 billion years? The process is called decomposition. Dead animals and plant decompose and become detritis. Eventually plants become oil or coal with time and heat. \n\nTen Years from now? What the hell do you mean by that?

I dont agree with the first two answers, just because the plants dont get pollinated it doesnt mean they will die, they just will not be able to reproduce. \nIf all animals die, there will be a major disruption in 2 main cycles that could affect the ecology. The Nitrogen cycle, and the CO2 cycle. \n\nPlants use Carbondioxide for photosynthesis and give off oxygen.. where animals use oxygen and give off carbondioxide. any instability in this cycle would have detrimental effects.\n\nNitrogen cycle.. ammonia based compounds in the soil mostly from animal waste are converted into nitrites and nitrates by specific bacteria  so that they are absorbed by the plants...without animals, there would be a major imbalance.

A huge die-off caused either by a plague, or poisoned water, or starvation. The planet will turn on us and wipe us out. Then it will start all over again with bacteria and salt water.

one organisms loss is anothers gain...meaining the death of one organism provides food for another. Also can translate into evolution. The extinction of one organism is the result of the evolution of another

DNA changes over a long period of time by different factors such as the temperature. For example, During the ice age, the organisms have tough skin, heavy fur to keep their body temperature warm. Then the earth warmed up so the these organisms no longer need the heavy fur to keep warm. Their children's children began to evolve to have less fur in order to not die of heat. The organism changes when its surroundings/environment change. Evolution is needed for the organisms to adapt and survive to the current living conditions presented upon them.

As soon as death occurs, decomposition starts.  They float because of the build up of gasses in the lungs and digestive tract.

Just a guess here, but I suspect an attentive gardener or farmer would actually stop the succession of the environment.  Because they are looking ofr one particular plant in an area, they eliminate all the others that try to grow in the natural way (weeds, trees, grasses, etc.), leading to a cessation of succession.

An Estuary is a broad mouth of a river into which the tides flows.An ecosystem is a self supporting unit dat is made up of a living part and a dead part.In other words both r interrelated.In the ecosystem,der is the transfer of energy and a recyclin of inorganic nutrients.Hence,if estuary was destroyed,the organisms dat thrive der like d Arenicola worm and the mitten crab would equally die.In the sense dat der will b no transfer of energy to keep dem alive neither would der be any recycling of nutrients.And as even u cant live for very long without food even if u take water.They therefore die.

Biotic factors are not only the organisms themselves, but also their relationship and effect on the surroundings. For example, forest soil aeration might be caused by worms living underground, which might help the trees grow better, etc.

I don't really know.... my guesses would be regulating the fish population. I think a negative effect might be that fact that because they're an endangered creature wherever they build their nests, they can't be moved regardless of how inconvienet it is to people.
