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.

The only statement that is true about exponential growth is:

a) Exponential growth curves are common for R-selected species.

Population growth in r - selected species grow/decay according to the exponential growth equation:

Delta N / Delta t = rN

We know that in reality, it is not possible for population growth to continue indefinitely.
