Question

Models can be many things. The four graphs you see here are population models. All four graphs have something in common. What is it?
Responses
A The graphs show exponential population growth.The graphs show exponential population growth.
B Each graph shows the birth and death rates over time.Each graph shows the birth and death rates over time.
C Each graph shows the change in population(s) over time.Each graph shows the change in population(s) over time.
D All four graphs show how species compete for resources.

Answer 1

C — Each graph shows the change in population(s) over time.

Explanation: all four plots are population models, so they depict how population size(s) vary as time progresses (whether growing, declining, oscillating, or interacting), not necessarily all exponential growth or birth/death rates specifically.
