APBIO-ISYGJV

In the Earth's history, there have been events that have occurred that have resulted in major changes in the species on the planet.

What is one theory that describes one of these events, and what was the change?

A

A meteor hit the Earth resulting in the death of organisms. The result was the extinction of many larger organisms because of the impact of the meteor.

B

A major virus infected the larger organisms on Earth, resulting in their deaths.

C

A meteor hit the Earth, resulting in dust that blocked the ability of the sun's energy to reach Earth. The result was the extinction of the larger organisms because of their need for a large amount of energy.

D

A meteor hit the Earth, resulting in dust that blocked the ability of the sun's energy to reach Earth. The result was the extinction of the larger organisms, because the dust poisoned the plants and animals that the larger organisms depended on for energy.
