Question

HELP!!! 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.

Answer 1

b, c, and d seem wrong, although eventually all growth curves must go from exponential to something that levels off

exponential is n(t) = n(0) exp(kt)

s-shaped curves may have initial exponential regime.

Answer 2

A
