        ECOSYSTEMS

A limiting factor is anything in an ecosystem that limits the population of animals in it. An example of a limiting factor would  be if there are to many of one animal in an ecosystem there will not be enough food for all of them and some will leave the ecosystem. Some limiting factors are: food, water, shelter, tempature, population, predators, water tempature, climate and more. An ecosytem is a certain place were a varity of certain animals live a work together. Symbiosis is the interaction between animals. The three types of symbiotic relationships and their defintions are: Mutualism is when both animals benefit from their relationship, Commensulism is when one animal benefits and the other is not affected,  Parasitism is when one animal benefits and the other is harmed. Ecology is the study of ecosystems and how they work.   It is important to have many speicies of animals in an area because without the predator/prey relationship and so few animals in the area they would all die out after a while.
