Question

Rainfall in a tropical region is below average for 10 consecutive years. Insect species adapted for dry conditions are much more plentiful at the end of 10 years. Which of the following statements best explains the increase in the poplulation of these insects?

Answer 1

They adapted over the years and reproduced more, the rain could have possibly made it harder for them as they are so small.  Also with lack of water bigger animals that feed on the insects may be decreasing in population due to the lack of water they are used to, thus the insects have less predators to worry about. I hope this helps.
