EVERYDAY SCIENCE

Detailed explanation-1: -Density independent factors, on the other hand, affect the population, regardless of the density of the population. Density independent factors tend to be abiotic factors, such as storms, floods or harsh winters.

Detailed explanation-2: -Among the given options, winter storms affect the population in density independent manner as it can affect the individual organism. For example, winter storm causing the death of a deer regardless of deer population density.

Detailed explanation-3: -These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons.

Detailed explanation-4: -It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.

Detailed explanation-5: -Competition within the population. When a population reaches a high density, there are more individuals trying to use the same quantity of resources. Predation. Disease and parasites. Waste accumulation.
