Which environmental factor limits the growth and size of a population?

Which environmental factor limits the growth and size of a population?

• A. Carrying Capacity
• B. Limiting Factor
• C. Succession
• D. Pioneer Species

Answer: (B)

Limiting factors are environmental influences that prevent a population from growing indefinitely. When essential resources like food, water, space, or mates become scarce, or when predators, disease, or harsh conditions are present, growth slows or stops. These factors set a ceiling on how large a population can be at a given time, because survival and reproduction are restricted by these conditions. Limiting factors can be biotic (such as competition or predation) or abiotic (such as drought or extreme temperatures). If the limiting factor eases, the population can increase again, up to the limits imposed by the environment. Carrying capacity refers to the maximum population size the environment can sustain over the long term given these limits. Succession is the gradual change in community structure over time after a disturbance, and pioneer species are the first organisms to establish in a new or disturbed area.
