DEFINITION OF ECOSYSTEM: An ecosystem is a complex set of relationships among the living resources, habitats, and residents of an area. It includes plants, trees, animals, fish, birds, microorganisms, water, soil, and people.
Ecosystems vary greatly in size and the elements that make them up, but each is a functioning unit of nature. Everything that lives in an ecosystem is dependent on the other species and elements that are also part that ecological community. If one part of an ecosystem is damaged or disappears, it has an impact on everything else.
The elements of a ecosystem are make up by non-living things or abiotic part, like the weather or temperature, and the living factors or biotic part.

When we think of nature we usually think of living things such as plants and animals, the biotic components of an ecosystem include all the living things in an area.
This is a monarch butterfly and this is tiger swallowtail butterfly .
You decide: Why are these butterflies different from each other? These butterflies are members of two different species.
A Species c_ _ _ _ _ _ _ of a g_ _ _ _ _ of o_ _ _ _ _ _ _ _ w_ _ _ _ c_ _ s_ _ _ _ _ _ _ _ _ _ _
r_ _ _ _ _ _ _ _ a_ _ _ _ t_ _ _ _ _ _ _ _ _. Members of the same species possess similar characteristics. They often appear and behave similarly, like these Canada geese.
A g_ _ _ _ of t_ _ s_ _ _ s_ _ _ _ _ _ in a s_ _ _ a_ _ _ i_ c_ _ _ _ _ a population, for example the water lilies in this pond make up a water lily population. And the geese in this field make up a population, as to the turtles in this pond. Rarely in nature is a single population of organisms the only population in a place, for example in this wetland located in the Florida Everglades, there are populations of alligators and hinges, fish and water lilies to name just a few. All these different populations of living things make up a community.
A Community c _ _ _ _ _ _ _ of a_ _ t_ _ l_ _ _ _ _ o_ _ _ _ _ _ _ _ i_ a_ a_ _ _ . Ecologists often categorize areas by natural communities.
A Natural community c_ _ _ _ _ _ _ of all t_ _ p_ _ _ _ _ a_ _ a_ _ _ _ _ _ i_ _ _ _ _ _ _ _ _ _
w_ _ _ t_ _ _ _ e_ _ _ _ _ _ _ _ _ _. The definition of a natural community is similar to that of an ecosystem. But the size of an ecosystem is variable from small as a tiny pool to as large as an entire mountain range.
Ecologists tend refer to natural community in more localized areas such as hillsides, swamps or forests. For example this community is referred to as a hemlock forest. It´s called that because hemlocks are the dominant tree although many others plants and animals are found here.
