Question

In the given food web, an increase in the population of hawks will not result in

• A. Decrease in the population of rabbits and snakes
• B. Decrease in the population of producers
• C. Decrease in the population of lizards
• D. Increase in the population of grasshoppers.

Answer 1

Answer: (B)

Decrease in the population of producers

Answer 2

An increase in hawks will increase predation on their prey (rabbits, snakes, lizards), causing their populations to decrease. With fewer lizards preying on grasshoppers, the grasshopper population is likely to increase. However, producers (grass) are not directly preyed upon by hawks. In fact, due to reduced herbivory from some consumers, the producer population may increase rather than decrease. medium Biology Ecosystem Food Webs and Trophic Levels single_choice
