What is an Eco-system

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.
