Which of the following statements about exponential growth curves is true?
a. exponential growth curves are common for r-selected species.
b. exponential growth curves show fast growth rates followed by slow growth rates.
c. no organisms in nature experience exponential growth rates.
d. exponential growth curves are s-shaped.

a.Exponential growth curves are common for R-selected species is a correct answer.

Explanation:

Exponential growth defines as the increase in number by a constant proportion.

The exponential growth curve is formed when the resource is more for the population with a particular type species.

In the exponential phase growth rate is the same for each species in a population it results in the rapid increase in the population growth and increases in the size.

The exponential curve is J in shaped and it is seen in R selected species.

R selected species are the species which have a very short life and reproduction rate is very high.
