Question

Often the growth cycle of one population has an effect on the cycle of another. As moose populations increase, for example, wolf populations also increase, which will then reduce the moose population. Thus, if we are considering the logistic equation for the wolf population, which of the factors accounts for the effect of wolves on the moose population

Answer 1

K (carrying capacity)

Explanation:

In logistic growth, the population growth decreases as population size approaches its maximum value, i.e., when the carrying capacity of the environment is reached. In consequence, the carrying capacity can be defined as the maximum population size in a particular environment, which depends on a given resource (e.g., food, habitat, water, etc).

The logistic equation for logistic growth is: dN/dt = rN [K - N/K] >>

dN/dt = change in population size in a given time interval

N = population size

r = intrinsic rate of increase

K = carrying capacity
