A scientist observes a population crash among eagles within an island ecosystem. Which event might have led to such a crash?

Travelers brought new crops to the island.

A drop in sea level exposed more of the island.

The closing of a dam caused the island to flood.

Warm weather conditions resulted in an abundance of food.

The closing of a dam caused the island to flood.

Explanation:

A population crash is a sudden decline in the numbers of individual members in a population, species or group of organisms. This can be caused by disease, environmental stress (such as pollution), or when its numbers exceed the carrying capacity of its habitat.

Of the four options, the one that would result in the destruction of the habitat and ecosystem which supports the population of the eagle would be flooding of the island due to the closing of a dam.
