Which of the following is an example of a density-independent factor limiting population growth? a. a forest fire that was caused by lightning b. the presence of predators c. an outbreak of wasting disease in elk d. competition for food

Answer;

A forest fire that was caused by lightning

Explanation;

-Density-independent factors are factors such as weather and climate, that exert their influences on population size regardless of the population's density. In contrast, the effects of density-dependent factors intensify as the population increases in size.

-Density-independent limiting factor have the same effect regardless of population size, for example - If there is a wild fire, the fire destroys all the animals in the forest regardless of how many animals there are. The fire does not care how big the population is.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.
