Plz help me with this question which of the following had a major impact on the development of the early atmosphere. may be more than one

A.) Photosynthetic organisms began to reduce carbon dioxide.

B.) Nitrogen consuming organisms began to consume carbon dioxide.

C.) Photosynthetic organisms began to produce oxygen.

D.) Nitrogen consuming organisms began to reduce carbon dioxide.

E.) Photosynthetic organisms began to produce carbon dioxide.

F.) Nitrogen consuming organisms began to produce oxygen.

Photosynthetic organisms began to reduce carbon dioxide and photosynthetic organisms began to produce oxygen.

Explanation:

Earth's early atmosphere was much different than the one we know of today. It was a type of atmosphere that did not provide conditions for larger life forms to develop, but this all change thanks to the first microorganisms on the planet. Even though extremely small, the cyanobacteria spread out across the planet and dominated it, but what's more important is that it used the process of photosynthesis, which changed Earth's atmosphere forever.

The cyanobacteria, in order to perform the process of photosynthesis, needed carbon dioxide, so it was obtaining it from the atmosphere. Once used for its purposes, the cyanobacteria were releasing the oxygen of the carbon dioxide back into the atmosphere. This resulted in a reduction of the carbon dioxide levels and an increase in the oxygen levels in the atmosphere, so over the course of a very long period of time the atmosphere changed drastically, and it provided conditions for other, larger organisms to start developing.

i do believe that its called,(the segovia highlands); plz check first good luck;

the answer to this question is give me a better question
