What term describes when a population temporarily exceeds carrying capacity?

• A. Population declines as soon as carrying capacity is reached.
• B. Overshoot occurs when population temporarily exceeds carrying capacity.
• C. Carrying capacity increases automatically after overshoot.
• D. The ecosystem becomes more productive during overshoot.

Answer: (B)

Carrying capacity is the maximum population size that the environment can support over time with available resources. When a population grows and temporarily surpasses that limit, the situation is called overshoot. This happens because population growth can outpace the environment’s ability to provide enough food, water, and space, and the effects of resource limits take a little time to show up. After overshoot, resources are stressed, and the population often declines or fluctuates as the system moves back toward a level the environment can sustain. So the term that describes this temporary crossing of the limit is overshoot. The other statements don’t fit because immediate decline at the moment capacity is reached isn’t required, carrying capacity doesn’t automatically increase right after overshoot, and overshoot doesn’t imply the ecosystem becomes more productive—it typically signals resource strain.
