The correct answer is - cyanobacteria.
The atmospheric oxygen came from the cyanobacteria. These were one of the earliest living organisms on Earth. The cyanobacteria was using photosynthesis in order to create its own food. The photosynthesis process requires sunlight, carbon dioxide, water, and oxygen. The oxygen is mostly released as a waste product from the process of photosynthesis, thus the cyanobacteria were literally releasing oxygen that was ending up into the atmosphere. As more and more cyanobacteria there were across the planet, more and more oxygen they were releasing into the atmosphere, slowly changing the composition of the atmosphere, and setting the basis of it as we know it now.

Answer:
Tilt = 23 1/2 (Florida Summer)
Tilt = 0
Tilt = 23 1/2
Tilt = 45
Tilt = 90
Explanation:
- From the most daylight to the least daylight the tilt of the planet on its axis will form the 23 and a half in the northern hemisphere that gets most of the sun and the equator as 0 degree has amp;e of sunlight through the day in north and south side and the winter again in the southern hemisphere as 23 and half degree.
- The angle of the 45 degrees s darkness as in the winter season and due to the titled nature of the axis and the distance from the sun. And the angle of 90 degrees again has darkness as the sun is too far and daylight becomes shorter with the extremes.
