question 2 of 10
which best describes the ecosystems on earth?
a. separate ecosystems can affect each other.
b. earth has mostly rain forest ecosystems.
c. ecosystems do not interact with each other.

Ecosystems are interconnected. For example, air quality (which can be influenced by one ecosystem's industrial activities) can affect another ecosystem. Rainforest ecosystems are a significant but not the majority type on Earth (so B is wrong). Ecosystems do interact (so C is wrong). Earth has a vast number of ecosystem types (so D is wrong).

A. Separate ecosystems can affect each other.
