In a food web what happens to the energy stored in foods by producers?
602892
Producers, which are usually plants and other photosynthetic organisms such as some types of bacteria, are consumed by primary consumers, so the energy enters the system of the primary consumer (like a rabbit, for example) and some of the energy is used up to power the animal's system (metabolism, etc). Then secondary consumers (picture a fox) eat the primary consumer, and with it the remaining energy that was not used up by that primary consumer. Then tertiary consumers... etc. etc. The pattern continues.

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.

Pardon me if I am incorrect but i dont think that plants NEED more energy rather they HAVE more energy. Each time you move up the food chain, only 10% (?) of the original energy the organism had is retained. The rest is lost. Since plants are at the bottom of the food chaing and are autotrophs, they receive 100% of the energy they converted through photosynthesis. Then the rabbit who eats the plant gets only 10% of that and the fox who eats the rabbit gets only 1%.

Prey feeds the predator.\nPredator keeps #s of prey down so as to remain within their food supply limits.\nThe more food, the more prey, the more predators.\nThe more predators, the less prey.\n\nThe system stays in balance.

The energy that carnivores obtain from their diet is the chemical energy of molecules in the food.  As they metabolize (oxidize) food molecules, energy is released which is trapped and temporarily stored in the form of ATP molecules.\n\nPlants, on the other hand, absorb light.  The chlorophyll and other pigment molecules in the chloroplasts absorb light, and through the processes in chloroplasts, they are able to use that light energy to produce ATP and to produce electrons that are then available for use by the cell.

An aboitic facotor is some non-living factor in the envirnoment that the organism cannot control. For a plant tempuratue, sunlight, etc. A plant ecosystem is basically the plant makes the food in photosythesis, gets eaten(others may eat the plant eaters), decomposers break down  dead consumers, and it starts over. Plants are primart producers. The first thing to eat them are primary consumers then secondary consumers get the idea.

There is a finite amount of energy in the ecosystem, regulated by the amount of sunlight plants can convert to usable forms of energy.  As you go up the food chain, a bit of this energy is lost at each level, meaning that at or above a certain trophic level, the energy input is insufficient to support an organism.  It's pouring water from bucket to bucket... You're going to spill some each time, and eventually, none will be left to pass on.

The energy contained in corn is in the form of stored chemical energy (in the form of hydrocarbons), that was created by solar energy and photosynthesis of the corn plant. \n\nThe seeds of corn can be made into sugar, food, ethanol, or even burnt alone as fuel. Each of these products contains hydrocarbons that contain chemical energy that can be converted to heat energy. Some new work is being done to convert the rest of the corn plant to ethanol or other sources of energy. It was common to burn corn cobs during the depression as fuel to heat homes. Today, they may be converted to alchohol fuel for automobiles using genetically engineered yeast. Shell Global Solutions and Iogen in Canada have built a demonstration plant to create ethanol from cellulose, which could include the entire corn plant, or other plant materials like wheat straw that shows great promise for producing environmentally-friendly economic fuel.

as far as plants are concerned they have a storage area in their cell known as VACUOLES within which the food is stored and used when required.\n\nand for animals there r only few aninmals who really store the  food. straight forward e.g are of a camel, bulls having hump at their back to store the food for future use

Food chains describe the feeding relationships in a biotic community. It is also called the energy chain because it describes the flow of energy and material from one species to another ie from plants to animals.\n\nA food chain describes a simple flow of material. It starts with the plant and algae who convert energy from the sun and ends with a top predator. For the Arctic or Southern ocean, a food chain may run as follows: Plankton-Copepod (small animal that feeds on plankton-fish-squid-orca.\n\nBecause energy is lost at each level, the number of levels in the chain does not normally exceed four or five. In overpopulated areas, people often cut one step from the food chain by eating grains themselves rather than feeding them to livestock. This increases the amount of food available. The loss of energy also explains why there are more plants and algae than herbivres and more herbivores than carnivores.\n\nThe food chain often doesn't reflect the complex relationships within an ecosystem. In reality, you have a complex flow of relationships. To reflect this, you have a food web or foot network that shows a complex flow of relationships. (I assume this is what you mean by a food pyramid which is normally related to human diet).\n\nGood luck with the report.

Carbon dioxide is used by the plant to produce glucose in the dark reactions of photosynthesis.  Without carbon dioxide the plants would be rather usless in the food chain.\n\n\nAll answers are correct.  Producers are the source of food for the next trophic level up.  Energy transfer is about 10% from level to level, with the rest going off as heat.  It would be bad news if there were more organisms above the others in the pyramid.  this would help lead to total extinction of life as we know it.

A food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees & shrubs, the giraffes (that eat trees & shrubs), and the lions (that eat the giraffes). Each link in this chain is food for the next link. A food chain always starts with plant life and ends with an animal.\n\n\nPlants are called producers because they are able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water.\n\nAnimals cannot make their own food so they must eat plants and/or other animals. They are called consumers. There are three groups of consumers.\n\nAnimals that eat ONLY PLANTS are called herbivores.\n\nAnimals that eat OTHER ANIMALS are called carnivores.\n\nAnimals and people who eat BOTH animals and plants are called omnivores.\n\n\nThen there are decomposers (bacteria and fungi) which feed on decaying matter. \n\nThese decomposers speed up the decaying process that releases mineral salts back into the food chain for absorption by plants as nutrients. \nDo you know why there are more herbivores than carnivores? In a food chain, energy is passed from one link to another. When a herbivore eats, only a fraction of the energy (that it gets from the plant food) becomes new body mass; the rest of the energy is lost as waste or used up (by the herbivore as it moves). Likewise, when a carnivore eats another animal, only a portion of the energy from the animal food is stored in its tissues. In other words, organisms along a food chain pass on much less energy (in the form of body mass) than they receive.\n\nBecause of the large amount of energy that is lost at each link ... \nThe further along the food chain you go, the less food (and hence energy) remains available\n\nThe energy pyramid shows many trees & shrubs providing food and energy to giraffes. Note that as we go up, there are fewer giraffes than trees & shrubs and even fewer lions than giraffes. In other words, a large mass of living things at the base is required to support a few at the top.\nMost food chains have no more than four or five links.\n\nThere cannot be too many links in a single food chain because the animals at the end of the chain would not get enough food (and hence energy) to stay alive.\n\nMost animals are part of more than one food chain and eat more than one kind of food in order to meet their food and energy requirements. These interconnected food chains form a food web.

it always belongs to the PRODUCERS--the ones that are photosynthetically active. the cycle goes this way: light energy is used by the producers in producing starch to be made available to herbivores, the primary consumers. the secondary consumers (a carnivore) consume the primary consumers and are eventually eaten by the carnivores (the ones belonging to the highest trophic level).

A FOOD CHAIN represents the movement of organic material from one trophic level to the next, from the Producers (Plants) to Primary Consumers (herbivorous animals) to Secondary Consumers (carnivores) etc.\nA FOOD WEB shows how the food chains in an ecosystem are linked together.\n\nSo in your question, start with the plant and link things together:\n\nSunlower --> rabbit ------>human\n         --> deer --------> ?\n         --> grasshopper -> ?\n\nNOTE: can't be shown here in text, but 'sunflower' has three arrows pointing away from it; each organism is only written once.
