The graph below shows two different deer populations over the same ten year period.
arsen [322]

Answer: D. The red line demonstrates an exponential growth rate, because the growth rate for the deer population is itself continuously increasing​.

Step-by-step explanation:

An exponential growth rate is one where the population in question is growing at a rate that continues to increase instead of remaining stable. That is, the growth rate itself grows.

The blue line does not show an exponential growth rate because the growth rate is stable per year. This is unlike the red line which grows at a rate that is increasing such that by the 4th year it's numbers cannot even be shown on the graph any longer.
