Plant respiration will increase. Animals will be forced to migrate. Soil nutrients will be enriched. Natural succession will cease.
I gave my students this multiple choice question: How will a thriving grassland ecosystem most likely be affected by a drought?

Only one answer is correct among these 4 choices:
- Plant respiration will increase.
- Animals will be forced to migrate.
- Soil nutrients will be enriched.
- Natural succession will cease.

Could you tell me which one is correct?

Animals will be forced to migrate.
