4. Human Populations

Carrying Capacity — Quiz

Test your understanding of carrying capacity with 5 practice questions.

Practice Questions

Question 1

Which of the following scenarios best illustrates a population that has exceeded its carrying capacity and is now experiencing a significant decline due to resource depletion?

Question 2

In the context of population dynamics, what does the term 'environmental resistance' primarily refer to?

Question 3

A population of fish in a lake has a carrying capacity ($K$) of $1000$ individuals. If the current population ($N$) is $800$ and the intrinsic rate of natural increase ($r_{max}$) is $0.3$ per year, what is the approximate population growth rate ($dN/dt$) using the logistic growth equation: $\frac{dN}{dt} = r_{max} N \left(1 - \frac{N}{K}\right)$?

Question 4

Which of the following human activities is most likely to significantly decrease the carrying capacity of a terrestrial ecosystem for a wide range of native species?

Question 5

In a forest ecosystem, a population of squirrels relies heavily on oak acorns as a primary food source. If a prolonged period of unusually cold weather severely reduces the acorn harvest for several consecutive years, what type of limiting factor is the acorn availability for the squirrel population?
