Question

How did the success of photosynthesis bacteria change earths atmosphere?

decreased hydrogen concertation
increased oxygen concertation
decreased oxygen concertation
increased hydrogen concertation

Answer 1

The success of photosynthetic bacteria, specifically cyanobacteria, played a significant role in changing Earth's atmosphere. These bacteria were able to convert sunlight, water, and carbon dioxide into oxygen through the process of photosynthesis. Over millions of years, the accumulation of oxygen in the atmosphere led to a rise in its concentration, while the concentration of other gases, such as hydrogen, decreased.

Therefore, the correct answer is:

- Increased oxygen concentration
