Carrying capacity refers to which concept?

• A. The maximum size of population the environment will support.
• B. An increase in the number of people who inhabit a territory.
• C. The level of pollution generated by a population.
• D. The rate of economic growth in a region.

Answer: (A)

Carrying capacity is the largest population size an environment can sustain indefinitely with its available resources and its ability to absorb wastes. It depends on factors like food, water, space, shelter, and ecosystem health; as a population grows, resources become limiting, causing growth to slow and stabilize as equilibrium is reached. If the population overshoots this limit, resources can be depleted and the carrying capacity can shrink, leading to declines or crashes. In farming and natural systems, carrying capacity helps explain why only a certain number of animals or amount of crop yield can be supported given the inputs and management in place, and how improvements in technology or resource management can raise it or degradation can lower it. The other ideas describe growth, pollution, or economic trends, not the sustainable limit set by resources.
