Answer 1

The correct answer is - B. The native plants and animals that live there.

When there's a group of plants and animals that is interconnected and are dependent  on each other in order to survive, than we have a separate and unique ecosystem. Even a slight disturbance in the ecosystem can have devastating effects on the whole of it because everything in it is connected.
