What would happen if prey were removed from the food web?
a. the population of predators would increase.
b. the population of predators would decrease.
c. the population of predators must stay the same.
d. the population of predators would fluctuate.

The correct answer is- B. The population of predators would decrease.

Food web describes an interconnected network of food chain, where transfer of energy takes place among different organisms within an ecosystem.

Predators are primarily the wild animals that capture, kill, and consume other animals ( called prey) for obtaining energy ( that is as a source of food). If prey are removed from a food web, food source for predator will be reduced, causing a decline in the population of predators within food web.
