Carrying Capacity and Population Dynamics Quiz

How does exceeding carrying capacity affect a population?

• It leads to increased resources and improved survival rates.

• It causes a decline in resources and increased competition, leading to a population decrease.

• It has no effect on the population.

• It leads to a higher birth rate.

A population of rabbits is introduced to an island with plenty of food and no natural predators. Initially, the rabbit population grew rapidly. Over time, however, the number of rabbits stabilizes, and there are no noticeable changes in the population size. What concept does this scenario best illustrate?

• Exponential growth

• Carrying capacity

• Density-dependent factors

• Logistic growth

A biologist is studying a population of fish in a lake. The biologist collects data on the fish population over several years and records the number of fish present each year. The biologist notices that the fish population fluctuates but remains relatively stable over time. Based on the data, what can be inferred about the fish population in the lake?

• The fish population is growing exponentially.

• The fish population has exceeded the carrying capacity of the lake.

• The fish population has reached a stable level around the lake's carrying capacity.

• The fish population is declining rapidly.
