Question

a volcanic eruption wipes out an entire ecosystem, reducing many populations in the area. what type of limiting factor is this? density dependent density independent

Explanation:

A volcanic eruption is a natural disaster. Density - independent limiting factors are environmental factors that affect population size regardless of population density. Volcanic eruptions fall into this category as their impact (like destroying habitats and reducing populations) is not related to how dense the populations were before the eruption.

Answer:

Density Independent
