What term defines the maximum number of individuals of a species that an environment can normally and consistently support?

• A. Carrying Capacity
• B. Limiting Factor
• C. Succession
• D. Primary Succession

Answer: (A)

Carrying capacity is the maximum number of individuals of a species that an environment can normally and consistently support over time, given the available resources such as food, water, shelter, space, and suitable conditions. As a population grows and approaches this limit, growth slows because resources become scarcer and density-dependent factors like competition, predation, and disease intensify. If the population overshoots, resources can be depleted and numbers drop back toward the carrying capacity, creating a balance around that level. Other terms don’t define a sustained maximum: a limiting factor is any resource or condition that restricts growth and can vary, while succession and primary succession describe the sequence of changes in community composition after a disturbance, not the fixed population limit.
