1)density dependent limiting factor
2)density independent limiting factor
3)immigration
4)emmigration

Answer 1

The correct answer is - 2) density-independent limiting factor.

Step-by-step explanation:

Density-independent limiting factors are the factors that cause a change in the size of the population without getting influenced by the density of the population.

Density-independent limiting factors include biotic or abiotic factors with catastrophic conditions such as natural disasters such as floods, earthquakes, drought, fires, and many more.

Drought affects the size of the population by increasing competition in the ecosystem for resources.
