When does the growth rate of a population following the logistic model equal zero ? The logistic model is given as dN/dt = rN(1-N/K):

A

When N nears the carrying capacity of the habitat.

B

When N/K equals zero.

C

When death rate is greater than birth rate.

D

When N/K is exactly one

Text Solution

Verified by Experts

The correct Answer is:
D
r-selected species are those that have a high growth rate , large number of offspring , small body size , early maturity , short generation time and ability to disperse offspring widely.

Keith modeled the growth over several hundred years of a tree population by estimating the number of the trees’ pollen grains per square centimeter that were deposited each year within layers of a lake’s sediment. He estimated there were 310 pollen grains per square centimeter the first year the grains were deposited, with a 1% annual increase in the number of grains per square centimeter thereafter. Which of the following functions models P(t), the number of pollen grains per square centimeter t years after the first year the grains were deposited?
