Question

Which of the following are density independent factors?

• A. Food
• B. Migration
• C. Predation
• D. Floods

Answer 1

The correct option is D Floods

Density dependent factors are factors that affect a population's growth differently depending on the density of that population. Food availability is a common density dependent factor affecting a population. Other common density dependent factors are migration, predation and availability of essential resources.
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.
