Hundreds of years ago, a volcanic eruption killed many plants and animals on a tropical island. Today, the island looks much as it did before the eruption. Why is this true? Destroyed ecosystems always return to their exact original state. Altered ecosystems only regain stability from the development of grasses. Geographic barriers prevent the migration of animals to island habitats. Destroyed environments can recover through ecological succession.

Destroyed environments can recover through ecological succession.

Explanation:

Ecological succession describes a progressive change in the species in an ecological community over time.

This can happen after some disturbance such as a fire, earthquake, or volcanic eruption. It can mean that a e can return to the state it was before the event.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
