Question 1 The graph shows the growth of fish and algae populations in a pond. Which of the following is true? a The growth of the algae population is nonlinear because it grows by a variable amount each week. b The growth of the algae population is linear because it grows by a variable amount each week. c The growth of the fish population is nonlinear because it grows by a variable amount each week. d The growth of the fish population is linear because it grows by a variable amount each week.

Answer 1

The correct answer is:

a) The growth of the algae population is nonlinear because it grows by a variable amount each week.

The graph shows that the algae population increases at a varying rate over time. Therefore, its growth is nonlinear.
