Question

The Serengeti plains are part of the African savanna ecosystem and are home to a variety of different species of plants and animals. The Serengeti plains experience a seven-month period of seasonal drought each year, during which the ecosystem receives only four inches of rain and the availability of some resources becomes very scarce.

Which type of limiting factors does the seasonal drought in the Serengeti plains affect?
density-independent factors
density-dependent factors
population-dependent factors
population-independent factors

Answer 1

density-independent factors

Explanation: Seasonal drought is an abiotic factor that affects populations regardless of their density (it reduces water and food availability for all individuals), so it is a density-independent limiting factor.
