What does the slope represent in a graph that plots prey population (Npᵣₑᵧ)against the per capita consumption rate of predation?
A)efficiency of predation (c)
B)efficiency with which food is converted into predator reproduction (b)
C)predator population growth rate (r)
D)the rate of increase in prey availability

Question

Quizplus · Accepted Answer

The slope of the graph represents the rate at which the prey population declines with increasing per capita consumption rate of predation. This rate is known as the efficiency of predation (c), which is the proportion of consumed prey that is converted into predator biomass. Therefore, A is the best choice. B is incorrect because it refers to the efficiency of converting food into predator reproduction, which is not directly related to the slope. C is incorrect because it relates to the growth rate of predator population, not the relationship between prey population and consumption rate. D is incorrect because it refers to the rate of increase in prey availability, which is not represented by the slope on this graph.
