question 33

Multiple Choice

In the Lotka-Volterra Model,there are numerous factors that determine the populations of the two competing species.If we were to graph the zero isoclines of two competing species,such as the baboon and cheetah,then we can learn how each population's size will be affected under certain ecological circumstances.Using the notation for the model from the text,what would happen to the population of baboons (species 1) and cheetahs (species 2) if K₂ > K₁ α₂₁ and K₂α₁₂<K₁?

• A) Baboons would go extinct and cheetahs would reach their carrying capacity
• B) Cheetahs would go extinct and baboons would reach their carrying capacity
• C) Cheetahs and baboons would reach stable equilibrium populations and competitively coexist
• D) Both answers a and b are possible, but it is not possible to determine which without more data
