APFIVE Modeling Species Richness During Succession
Which of the following is an example of a function that models the change in species richness over time in an ecosystem undergoing succession?
A
An exponential function, $$R(t) = 50 * e^{0.1 * t}$$, that continuously increases species richness.
B
A constant function, $$R(t) = 50$$, indicating unchanging species richness over time.
C
A quadratic function, $$R(t) = -2 * (t - 10)^2 + 50$$, that increases to a maximum and then declines.
D
A linear function, $$R(t) = 3 * t + 20$$, which lacks a peak representing decline.
