The correct answer is B. biotic potential.
Biotic potential is the maximum rate of increase in a population under ideal conditions. It is the theoretical maximum number of offspring that a population can produce in a given time period. Biotic potential is often expressed as the number of offspring produced per individual per unit time.
C. carrying capacity is the maximum number of individuals of a species that a particular environment can support indefinitely. It is determined by the availability of resources such as food, water, and shelter.
D. K value is the population size that is in equilibrium with the environment. It is the point at which the birth rate and death rate are equal.
A. C value is not a term used in population ecology.
