Practice Questions

Question 1

Which of the following best describes the concept of 'population dynamics' in marine science?

Question 2

In the context of marine population growth, what is the primary difference between exponential and logistic growth models?

Question 3

A marine fish population experiences a sudden increase in the availability of its primary food source. Assuming no other limiting factors, which population dynamic is most likely to be immediately affected?

Question 4

Consider a marine population where the intrinsic rate of natural increase ($r$) is $0.08$ per year. If the initial population size ($N_0$) is $2000$ individuals and the population is undergoing exponential growth, what will be the approximate population size ($N_t$) after $2$ years? Use the formula: $$N_t = N_0 e^{rt}$$

Question 5

Which of the following factors is considered a density-dependent factor affecting the abundance of marine species?
