Oxygen in the atmosphere is essential for life on Earth, as it is necessary for cellular respiration in most living organisms. It supports combustion and helps maintain the balance of ecosystems by participating in various biochemical cycles. Additionally, oxygen contributes to the formation of the ozone layer, which protects the planet from harmful ultraviolet radiation.

What atmosphere we live on?
The main components of Earth's atmosphere are nitrogen and oxygen. Of these, oxygen is the one we can't live without.
Where did oxygen in the atmosphere came from?
Oxygen in the atmosphere primarily comes from photosynthesis by plants and other photosynthetic organisms. These organisms use sunlight to convert carbon dioxide into oxygen as a byproduct. Over millions of years, this process has led to the accumulation of oxygen in the Earth's atmosphere.
Do trees provide the most oxygen for the atmosphere?
While trees play a significant role in producing oxygen, they are not the sole source. Phytoplankton, algae, and other plants also contribute to oxygen production in the atmosphere through photosynthesis. Overall, terrestrial and aquatic ecosystems collectively contribute to the oxygen balance in the atmosphere.
