adapt to a changed landscape undergo ecosystem progression return to its pre-pollution conditions produce organisms that can survive changed conditions
I gave my students this multiple choice question: The removal of waste from Florida's East Bay and Pensacola Bay is intended to speed the bay ecosystem's natural tendency to do which of the following?

Only one answer is correct among these 4 choices:
- adapt to a changed landscape
- undergo ecosystem progression
- return to its pre-pollution conditions
- produce organisms that can survive changed conditions

Could you tell me which one is correct?

return to its pre-pollution conditions
