Answer 1

The best example that describes how a density-dependent limiting factor can affect a forest ecosystem is:

**A disease causes death of many animals in the forest.**

Density-dependent factors are those that have an increasing effect as the population density increases, such as disease, competition for resources, and predation. In contrast, the other examples (forest fire, earthquake, and poaching) are generally considered density-independent factors, as they can affect populations regardless of their density.
