How did early photosynthesis organisms change Earth's atmosphere?

Photosynthetic bacteria produced oxygen, and as they continued to colonize the earth they produced more oxygen. Eventually all the oxygen sinks became saturated, and this resulted in the Great Oxygenation Event (GOE). Aerobic organisms would late evolve and utilize the free oxygen.

What era did the atmosphere change due to living organisms?
The presence of organisms played a crucial role in shaping Earth's atmosphere. An organism must interact with the environment, taking in and producing material to sustain life. Early organisms took in carbon dioxide and produced sea sediment.

Organisms that change the energy in sunlight into food are called?
Organisms that produce their own food are called autotrophs. All plants are autotrophs and use photosynthesis to create their food.
How has the earths atmosphere changed?
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
