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 K₂α₁₂1? 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

The first inequality K₂> K₁ α₂₁ indicates that species 1 has a higher reproductive rate (B1) and a higher carrying capacity (K1) than species 2. This means that species 1 will be able to outcompete species 2 and reach a stable equilibrium population, while species 2 will decrease in population size until it reaches its carrying capacity (as indicated by the zero isoclines). The second inequality K₂α₁₂1 indicates that species 2 has a higher reproductive rate (B2) and carrying capacity (K2) than species 1. This means that species 2 will be able to outcompete species 1 and reach a stable equilibrium population, while species 1 will decrease in population size until it reaches its carrying capacity. Therefore, both species will reach a stable equilibrium population and competitively coexist.
