Question

What happened to $N H subscript 3 end subscript$ present in the primary atmosphere during its conversion to the secondary atmosphere?

It got oxidized to $H_{2}$ and water
It was absorbed by photoautotrophs
Most of it got oxidized to nitrogen oxides
It concentration was decreased due to $O_{2}$ formation

The correct answer is: It got oxidized to $H subscript 2 end subscript$ and water

Oxygen releasing photosynthesis organisms on the primitive earth similar to the existing blue-green algae (cyanobacteria). They used water to get hydrogen and released oxygen. Addition of oxygen to the atmosphere started oxidizing methane and ammonia, hence they began to disappear
$C H subscript 4 end subscript plus 2 O subscript 2 end subscript rightwards arrow C O subscript 2 end subscript plus 2 H subscript 2 end subscript O$

$4 N H subscript 3 end subscript plus 3 O subscript 2 end subscript rightwards arrow 2 N subscript 2 end subscript plus 6 H subscript 2 end subscript O$
