Which of the following is a density-dependent factor affecting population growth? (2019)

Step 1: Understand what density-dependent factors are. These are factors that affect population growth based on the number of individuals in a given area.
Step 2: Recognize that food availability is a resource that can be limited. When there are many individuals in an area, food becomes scarce.
Step 3: Realize that if there are fewer individuals, there is more food available for each one. This means that food availability changes based on how many individuals are present.
Step 4: Conclude that food availability is a density-dependent factor because its impact on population growth varies with population density.
