In population ecology, what does the term biotic potential of a population refer to?
A
The decrease in population growth rate caused by competition, predation, and disease
B
The maximum reproductive capacity of a population under ideal environmental conditions with unlimited resources
C
The maximum number of individuals an environment can sustainably support (carrying capacity)
D
The current population size after accounting for density-dependent limiting factors
Verified step by step guidance1
Understand that biotic potential refers to the inherent ability of a population to reproduce and increase in number under ideal conditions.
Recognize that 'ideal environmental conditions' mean unlimited resources, no predators, no disease, and no competition affecting the population.
Distinguish biotic potential from other related concepts such as carrying capacity, which is the maximum population size an environment can sustain.
Note that biotic potential focuses on the maximum reproductive capacity, not the current population size or factors that decrease growth rate.
Summarize that biotic potential is essentially the highest possible growth rate a population can achieve when not limited by environmental factors.
