Which term describes the maximum pest population a habitat can sustain?

• A. Maximum pest density
• B. Population limit
• C. Carrying capacity
• D. Habitat ceiling

Answer: (C)

Carrying capacity is the largest number of individuals an environment can support over the long term given the available resources like food, water, and shelter. For pests, this means the habitat can sustain that many individuals without degrading resources or harming the environment. When pest numbers approach this limit, growth slows and the population tends to stabilize near that level. If resources dwindle, carrying capacity drops and populations may crash; if resources improve, carrying capacity can rise again. This is the standard term for the sustainable maximum population, which is why it’s the best fit. The other phrases are not standard ecological terms for this concept and don’t specifically denote a long-term sustainable limit.
