Question

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.
please select the best answer from the choices provided
a
b
c
d

Explanation:

• Option b: Exponential growth has a continuously increasing rate, not fast-then-slow (that describes logistic growth).
• Option c: Some organisms in nature do experience short periods of exponential growth when resources are unlimited.
• Option d: S-shaped curves are logistic growth curves, not exponential (exponential is J-shaped).
• Option a: R-selected species have high reproductive rates, rapid growth, and often follow exponential growth patterns when resources are abundant, which matches the trait of exponential growth curves.

Answer:

A. Exponential growth curves are common for R-selected species.
