Question

An ecosystem cannot repair itself _____? after a volcanic eruption. after a flood. after a tornado. after a housing development is built.

Answer 1

after a housing development is built would be the correct answer. This is because manmade objects are obstructing the habitat- which forces the animals to relocate and prevents the vegetation from growing.

Answer 2

The correct answer would be after a housing development is built.

The other options like a volcanic eruption, flood, and tornado come under natural calamities which adversely affect the ecosystem and greatly reduce the population of species living there.

However, they do not eliminate the complete ecosystem. The damaged ecosystem undergoes secondary succession and repairs itself to produce a similar ecosystem that existed before the natural disaster.

In contrast, housing development (man-made changes) leads to the permanent loss of the natural habitat of wild animals and plants.

It is why an ecosystem can not repair itself after a housing development is built.
