which statement best describes ecosystem?
A. They can never change unless their established.
B They constantly change in different way's over time
C Ecosystems always revert back to their original state
D Each ecosystem can exist for only a specific length of time
i believe the answer is b, because the world is always changing and i don’t think it will ever stop. there will always be changes that we have to adapt to. so i think that ecosystems evolve over time slowly but surely.
