Select Which of the Following Choices are Correct

Question

Select which of the following choices are correct.
A) Predator populations can be impacted by other predators
B) When predator numbers increase there is often a density dependent negative impact on the predator species
C) The lynx and hare population cycles are easily explained by Lotka Volterra models
D) Parasites rarely interfere with one another

Accepted Answer

A is correct as predator populations can be impacted by competition with other predators for prey, as well as predation on each other. 
B is correct as an increase in predator numbers can lead to increased competition for resources, crowding, and disease transmission, which can have a negative impact on the population. 
C is incorrect as the lynx and hare population cycles have many factors at play and are not easily explained by Lotka Volterra models alone. 
D is incorrect as parasites often compete for host resources and can interfere with each other's survival and reproduction.
