Large Scale Event and Changes to the Biosphere

APBIO-MLHOVK

The great oxygen event was a large scale event that caused an increase in the Earth's atmospheric oxygen. This change in the environment of the biosphere caused the majority of the species on Earth to become extinct.

Which of the following explains why the great oxygen event did NOT kill all of the organisms on Earth?

A

All of the species on Earth occupy their own niche, which they are able to occupy because of the diversity of species due to their genetic makeup. This diversity allows certain species to survive changes to the environment.

B

All of the species on Earth occupy a niche; they are able to occupy any niche because of the diversity of species due to their genetic makeup. This diversity allows certain species to survive changes to the environment.

C

All of the species on Earth occupy their own niche, which they are able to occupy because of the diversity of species due to their environment. This diversity allows certain species to survive changes to the environment.

D

All of the species on Earth occupy their own niche, which they are able to occupy because of the diversity of species due to their genetic makeup. This diversity allows all species to survive changes to the environment.
