उत्तर
A decline in the numbers of prey causes a decline in the number of predators.
Explanation:
Predator populations are dependent on the availability of prey as a food source. When the prey population declines, predators face a scarcity of food, which leads to starvation, decreased reproductive rates, or migration, ultimately causing their numbers to decline as well.
