A) man
B) parasites
C) predators
D) available food
Correct Answer: C
Solution :
In nature the population of predator is quite small as compared to that of the prey the latter is never eliminated completely. The prey has high reproductive potential. If the latter is maintained for some period without predation. The population of prey individuals would go beyond the carrying capacity of the environment. The individuals would then become weak and the species undergo degenerating with time. The predator keeps the population of the prey under check so that an equilibrium is maintained. The prey also maintained its optimum activity and efficiency since only weak and sick individuals are removed by the predators.
