Which term describes the maximum population size the environment can sustain indefinitely?

• A. Biomass
• B. Carrying capacity
• C. Carcinogenic limit
• D. Ecosystem capacity

Answer: (B)

Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely given the available resources, space, and environmental conditions. It represents the balance point where births and deaths stabilize because resources like food, water, and habitat can support only so many individuals. As a population grows toward this limit, growth slows and can level off in an S-shaped (logistic) pattern; if it overshoots, resource scarcity often pushes the numbers back down, sometimes causing fluctuations around the limit. This concept is dynamic and can change with seasons, climate, or resource availability, making carrying capacity a moving target rather than a fixed number. Other terms don’t fit: biomass refers to total mass, not how many individuals the environment can support; carcinogenic limit isn’t related to population dynamics; ecosystem capacity isn’t the standard term used for this idea.
