Question

which of the following are density dependent factors? select all correct options competition for resources natural disasters disease predation

Explanation:

Density - dependent factors are biotic factors that depend on population density. Competition for resources (as population density increases, competition for limited resources like food, space intensifies), disease (more dense populations allow easier spread of disease), and predation (predators may focus on more dense prey populations) are density - dependent. Natural disasters are density - independent as they affect populations regardless of density.

Answer:

A. competition for resources, C. disease, D. predation (assuming the options are labeled as A: competition for resources, B: natural disasters, C: disease, D: predation)
