Ecosystem is a place where living organism and non-living organism exist.This organism helping each other in order to survive.
Some of the organism provides foods which is necessary for survival.an ecosystem is a complex set of relationship among living resources,habitat and residents of an area.It includes plants,trees,animals,birds,micro organism,soil,water and people.
Ecosystem vary greatly in size and elements that make them up,but each is a function unit of nature.Everything that lives in ecosystem is dependent on other species and elements that are also part of ecological community.If one part of ecosystem is damage or disappear,it has an impact of everything else.
When an ecosystem is healthy,scientist say it is sustainable.This means that all the elements are in balance and capable of producing themselves.there is usually biodiversity,meaning there are a variety of living organism and species in the environment.I found out that we must to take care of our ecosystem.
