NEWSELA-Biological Carrying Capacity Quiz

What happens when a species exceeds its biological carrying capacity?

• The species becomes overpopulated.

• The species becomes extinct.

• The species migrates to a new habitat.

• The species' population remains stable.

What other factors, besides competition for shelter and food, determine a species' carrying capacity?

• Environmental factors such as pollution and extinctions of prey species caused by humans.

• Only the amount of food available.

• Only the number of predators.

• Only the availability of water.

How do ecologists and biologists determine the carrying capacity of individual species?

• By weighing all factors such as food, shelter, and environmental impacts.

• By counting the number of predators.

• By measuring the amount of water available.

• By observing the migration patterns of the species.

What could be the consequence of not managing species' carrying capacity?

• Destruction of delicate ecosystems and the global food web.

• Increase in the number of predators.

• Increase in the amount of food available.

• Stability of the species' population.

What is the impact of humans on their own biological carrying capacity according to some scientists?

• Humans have already exceeded their own biological carrying capacity.

• Humans have not yet reached their biological carrying capacity.

• Humans have no impact on their biological carrying capacity.

• Humans have a decreasing biological carrying capacity.

What is one example of an environmental factor that affects carrying capacity but is not caused by natural processes?

• Pollution.

• Availability of water.

• Number of predators.

• Amount of food.

What is the role of predator-prey dynamics in carrying capacity?

• It is one of the complex interactions that affect carrying capacity.

• It has no impact on carrying capacity.

• It only affects the number of predators.

• It only affects the amount of food available.

What is the relationship between carrying capacity and species extinction?

• Managing carrying capacity helps prevent species extinction.

• Carrying capacity has no impact on species extinction.

• Carrying capacity only affects the number of predators.

• Carrying capacity only affects the amount of food available.
