A fib about ecosystems....
Ecosystems are made of cheese......
There are many ecosystems, in fact , a human body is considered as an ecosystem. Nature is also 1 of an ecosystem. And there is many others.
I DID THIS LAST CEMESTER!! THE ECOSYSTEMS ARE: FRESHWATER, SALTWATER, TUNDRA, AND I FORGET THE OTHER 1'S SORRY!!
Ecosystems
Ecosystems that are established on land (as opposed to Marine ecosystems).
