what is the importance of the grassland ecosystem?
490064
Grasslands are recognized by many as the most imperiled ecosystem worldwide. Native North American grasslands that once extended from Canada into Mexico and from the foothills of the Rocky Mountains to western Indiana and Wisconsin have dramatically declined in area. This document addresses the grassland bird needs and funding requirements of the Central Grasslands, because the largest percentage of grassland habitat occurs in this physiographic province. The Central Grasslands include the three commonly recognized grasslands.\n\nThe unique avian assemblages associated with grasslands are also in danger -- grassland bird populations have shown steeper, more consistent, and more geographically widespread declines than any other guild of North American bird species. \n\nBreeding Bird Survey (BBS) data from 1966-1993 indicate that almost 70% of the 29 grassland bird species adequately surveyed by the BBS had negative population trends. \n\nThe need for information on abundance, productivity, habitat use, seasonal distribution, and effects of management practices is widely recognized among resource managers. \n\nFavorite grassland birds like the Eastern and Western Meadowlarks, Mountain Plover, Burrowing Owl, Dickcissel, Cassin's Sparrow, and Lark Sparrow are declining. \n\nThis strategy identifies the most important Department of the Interior (DOI) information needs and funding requirements associated with conservation of Central Grassland birds that are ecologically restricted to upland habitats. The ultimate outcome will be to identify causes of grassland bird declines and to address them through better management. \n\nThe most important information needs for grassland bird conservation focus on: \n\neffects of habitat/landscape features \nspecies status assessments \nrangewide surveys \nmonitoring issues \neffects of agricultural policies \nwintering ground issues \n\nLots more info on the webpage below:

The answer to studing ecology was worded the simplest by Kofi Annan. "There is little chance of protecting the environment without a greater sense of mutual responsibility." \nThe world in which is made up ofdelicate and complicated systems, which need to be understood by everyone on one level or another. While it would seem some of it to be trivial, an informed public insures a healthier planet.

What really drives species into extinction is destruction of habitat.  A great deal of land is cleared every year of agriculture and new homes.  To preserve biodiversity people would have to curtail that practice.

it is important.  But what about it?

The usual example is that of a pond; a self-contained ecosystem.\nNow you need to do your learning and consider how the organisms depend upon one another.

I'd say pretty dang important.\nYou've got competition between plants for resources, like Nitrogen and Phosphorus.  You've got competition between birds for nesting sites.  Fish also play a role here; those that have gills better adapted to salty water can take oxygen out of the water more efficiently than fish that have gills more adapted to freshwater.

I'm not certain anyone but a biologist can answer this one correctly, but I'll take a stab: the organisms in any ecosystem are related to each other in a hierarchy, like a food chain. Other relationships are helping, symbiotic or parasitical relationships in which one organism's function allows another to live. An ecosystem thrives when all its organisms are in balance.

Plants survive by adapting to the environment.  If the local fauna is eating the plant, the plant will develop a toxicity to ward off such animals form dining on the plant or the plant will reproduce in such numbers that a bite here and there doesn't matter.\n\nThe trick comes in when the animal develops a bond with a particular plant and adapts to the toxicity and uses this plant toxin to form its own shield against its predators--such as Monarch Butterflies and Milk weed or Gulf fliterary butterflies and the corky stemed passion flower.

It is important because of the enviroment. The animals, the air quality all need to be very clean. If an area doesnt stay clean, the enviroment will become nasty

ecosystem? biosphere? biological community?

Botany is the scientific study of plants and their environment.  It includes genetics, biochemistry, physiology, anatomy at a gross (large) level as well as at a tissue and cellular level (microscopic) and includes intracellular things such as chloroplasts and other specialised cell contents.  \n\nBotany also deals with plants in their environment e.g. soils and the nutrients derived from the soil (minerals etc).  Other aspects of plant growth and development are important in relation to light, temperature, water, humidity, salinity etc.\n\nBotany may also include plant pests and diseases and the problems of poor soils.  In addition, adaptations to specific conditions e.g. salt, drought are covered.  Plants are useful to medicine as many medicinal chemicals are derived from plant leaves and other parts; likewise there are many poisons that are plant-based (e.g. some fungi).\n\nThe relationship between plants and animals e.g. for fertilisation (birds, bats, insects) and seed dispersal (birds, mammals) can be involved in botany too.\nInteresting subject!

Carbon dioxide is food for plants, more CO2, more assimilation.

What is a Biome?\n\nA biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region. Major biomes include deserts, forests, grasslands, tundra, and several types of aquatic environments. Each biome consists of many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome.\n\nAll living things are closely related to their environment. Any change in one part of an environment, like an increase or decrease of a species of animal or plant, causes a ripple effect of change in through other parts of the environment. \n\nThe earth includes a huge variety of living things, from complex plants and animals to very simple, one-celled organisms. But large or small, simple or complex, no organism lives alone. Each depends in some way on other living and nonliving things in its surroundings.

Grasses feed on mineral salts, carbon, and water from soil\nmosses have a kind of mix physiology allowing them to feed on non-organig substratum, and to keep water stored for a very long time span- yet not fully able to feed on their own\ncockroaches are able to eat any kind of organic matter left by other animals -including the snaps of that chestnut pie left on the table.\nbees use mainly sugar from plants and use a lot of energy to collect it within a highly organized system

Grass grows.  Grazing animals (herbivores) eat grass and convert it to flesh.  Meat eating animals (carnivores) catch and eat herbivores.  Carnivores die.  Bacteria, fungi and other micro-organisms cause decay.  The decay products help fertilse the grass so it can grow, and the process repeats.\n\nIt is a little more complicated than that, but the  basics are as set out above.

OH YEAH!  The abiotic things.  Community is the interaction of living species with each other, ecosystem is those interactions Plus interaction with abiotic factors (water, temperature etc).\nLet me make sure.\n\nYep Yep.  i think that's it
