Questions 19-22 are based on the figure below. Remember, the parameters in the predator and prey isoclines are a = efficiency with which prey are converted into predator offspring d = death rate of predators c = capture efficiency r = intrinsic population growth rate of the prey The straight vertical line represents the prey isoclines a. True b. False Below the dashed a. Predator population decreases b. Prey population decreases c. Predator population increases d. Prey population increases At point 'x' a. Predator and prey populations decrease b. Predator population decreases and prey population increases c. Predator population increases and prey population decreases d. Predator and prey populations increase At point 'y' a. Predator and prey populations decrease b. Predator population decreases and prey population increases c. Predator population increases and prey population decreases d. Predator and prey populations increase According to Lotka-Voltera competition model what is the condition for stable coexistence a. Inter-specific competition > intra-specific competition b. Inter-specific competition

Explanation / Answer

19. true

“isoclines” as a tool to understand the interaction between a prey and a predator

20.a

21.a

22.d

23.b

Lotka-Volterra model predicts that stable coexistence of two species is possible only when intraspecific competition has a greater effect than interspecific competition.
