Question

Normal No Spacing Heading 1Heading 2 1) Explain why energy reserves can make a population experience delayed density dependence. (Ch. 13) 2) Explain why populations tan be inherently cyclic. (Ch. 13) 3) Why does the probability of extinction due to stochastic processes decline as population size increases? (Ch. 13) 4) How could you experimentally test whether herds of African antelope affect the abundance of plants on which they graze? (Ch. 14) 5) In the classic experiments of C.F. Huffaker with mites and oranges, what mechanisms allowed the predator and prey populations to persist? (Ch. 14)

Explanation / Answer

1) Delayed density dependence explains a circumstance where population growth is regulated by negative feedback working with a time delay.

Some   density dependence factors are

Energy reserves help the population to continue to live or exist more than the carrying capacity.

In this way energy reserves make a population experience delayed density dependence.

2) Some populations are inherently cyclical because there is a lag between breeding time and the time of birth.
