Question

a forest fire destroys an area. a small population of trees and a large population of birds are both affected. which type of limiting factor causes this?
density dependent
density independent
population dependent
population independent

Explanation:

Density - independent limiting factors are environmental factors (like natural disasters such as forest fires) that affect populations regardless of their density (size). A forest fire is a natural disaster, and it impacts both the small tree population and the large bird population without being dependent on how many individuals are in those populations. Density - dependent factors depend on population density (e.g., competition, predation). "Population dependent" and "population independent" are not standard terms for this concept. So the correct factor is density independent.

Answer:

B. density independent
