a decrease in the erosion of riverbanks a decrease in the number of native plants an increase in the number of animal habitats an increase in the diversity of insect species
I gave my students this multiple choice question: Which event will occur in an area after a major flood?

Only one answer is correct among these 4 choices:
- a decrease in the erosion of riverbanks
- a decrease in the number of native plants
- an increase in the number of animal habitats
- an increase in the diversity of insect species

Could you tell me which one is correct?

a decrease in the number of native plants
