Question

Describe the effect that photosynthesizing prokaryotes had on the ancient atmosphere.

Answer 1

$\bold{\large{\underline{Answer\: \colon}}}$

Starting from the origin of life on earth.

The $\bold{prokaryotic}$ animal evolved rapidly in the water these was the single celled animal's comes in the nature for example $\bold{cyanobacteria}$ a single cell prokaryotic organism.


It's waste develop the higher amount of $\bold{oxygen}$ in nature when it increase rapidly the amount of oxygen was developed.

So, what happen if oxygen develop in higher amount?

The thick shield of oxygen formed and which scatter more sun light and it also causes oxygen toxicity and damage central nervous system.

But to fix this oxygen amount the $\bold{eukaryotics}$ develop who inhale and exhale. It balance the amount of oxygen on earth.

How this prokaryotic organism cyanobacteria develop oxygen?

Cyanobacteria is also known as $\bold{blue\: green\: algae}$ use sunlight , water and $\bold{carbon\: dioxide}$ and left waste as $\bold{oxygen}$ in atmosphere.

This all about the ancient atmosphere.
