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, microorganism, water, soil, and people.

Ecosystem vary greatly in size and the elements that make them up, but each is a functioning unit of nature.
Everything that live in ecosystem is dependent on the other species, and elements that are also part that ecological community. If one part of an ecosystem is damages or disappear, it has an impact on everything else.

When an ecosystem is healthy, scientists say it is sustainable. This means that all elements live in balance and all are capable to reproducing themselves. This is usually biodiversity, meaning that there are a variety of living organisms and species in that environment.

Since ecosystems can be as small as a single tree or as large as entire forest, there
are lots and lots of different ecosystems in the Upper Peninsula of Michigan. When
you want to talk about how a certain natural area functions together, you can call it
a biome. A biome is a very specialized ecosystem that only exists in a certain
area or climate. They are identified by factors like temperature, rainfall, soil type and
altitude.
