Intraspecific Competition and Herbivory by Deer Are Both Factors Affecting

Multiple Choice

Intraspecific competition and herbivory by deer are both factors affecting the population growth rate of a bushy plant.Assume the following variables: the per capita growth rate of the bush is 0.1 when population density is very low;c is the rate per individual plant per meter square by which the population rate decreases due to competition;B is the density of plants per meter square;p is the rate by which individual deer reduce the per capita growth rate of the plant;and D is the number of deer.If G is the growth rate of the plants after accounting for intraspecific competition and predation,what is the equation for G?

A) G = 0.1 + cB - pD
B) G = 0.1 - cB + pD
C) G = 0.1 - cD + pB
D) G = 0.1 - cD - pB
E) G = 0.1 - cB - pD
