"What does the competition coefficient in the Lotka-Volterra competition model describe"? A. The difference in the carrying capacities of two species B. The effect of adding one individual of a species on the population growth rate of another species C. The number of individuals needed to drive another species to extinction D. The area of zero population growth

The competition coefficient in the Lotka-Volterra competition model describes B. The effect of adding one individual of a species on the population growth rate of another species

Explanation:

The competition coefficient in the Lotka-Volterra competition model explains species competing for some common resource.  It explains the effect of adding one individual of a species on the population growth rate of another species. They will compete for food with the colonies located near to them. When using equations for predation, the base population model is exponential.

D. The area of zero population growth

Explanation:

Competition coefficient can be explained as the degree to which an individual of one species affects through competition. It can also be described as the growth or equilibrium level of a second species' population, relative to the effect of an individual of the second species.

The Lotka-Volterra model predicts that there could be a possibility of a stable coexistence of two species, only when intraspecific competition has a greater effect than interspecific competition.

In conclusion, the competition coefficient in the Lotka-Volterra competition model resulted in zero isocline, which shows one species having a growth rate (dN/dt) of zero.
