The net outcome of predator-prey interactions in the basic Lotka-Volterra models is that: a. the prey population declines and this causes the predator population to also decline.
b. the predator drives its prey to extinction and then goes extinct itself.
c. predator and prey populations eventually converge on equilibrium population sizes that are maintained into infinity.
d. predator and prey populations oscillate, with each predictably increasing and decreasing in response to the other.
