Question

Imagine you are a scientist at a state park in Dallas. What type of ecological problems might result from the air quality?

Fish in the wetlands of the park would die.
Plants and small animals might suffer, and some might die.
All plants would die, and birds would likely migrate.
Large animals would die in huge numbers.

Answer 1

"Plants and small animals might suffer, and some might die" would be the best option, since the poor air quality would most likely affect certain plants and not others--some of which would be used for food by small animals.
