an example of a density dependent limiting factor is...
A) an avalanche
B) The amount of available food
C) a sudden flood
D) a decrease in water due to drought.
(please don't guess)
Answers
An example of a density-dependent limiting factor is the amount of available food. Thus, the correct option for this question is B.
What is a density-dependent factor?Density-dependent factors may be defined as those factors that may significantly vary with the density of the population. These factors may affect a higher proportion of individuals when population densities are higher and a lower proportion when the population is lower.
Examples of these factors may effectively include food, competition, predation, parasitism, accumulation of toxic wastes, etc. While options like a sudden flood, a decrease in water due to drought, etc. may include examples of density-independent factors.
Therefore, an example of a density-dependent limiting factor is the amount of available food. Thus, the correct option for this question is B.
