question 41

Multiple Choice

If a healthy ecosystem experiences a drought for several years, and then the normal rain pattern returns what would you expect to happen?

• A) A healthy and stable ecosystem will recover from the drought and quickly return to its previous state once the rains return.
• B) A healthy and stable ecosystem will recover from the drought once the rain returns, but most of the plants that were there will have been replaced by new species.
• C) Even a healthy ecosystem cannot recover quickly from an extended drought. I will recover but with an entirely new suite of species.
• D) There is no way for an ecosystem to recover from an extended drought. New drought-resistant plant species will have taken over and the original animal species will have moved out or died off.
