respiration
The atmosphere surrounding Earth provides oxygen for living organisms to breathe and carry out cellular respiration, which is the process that releases energy from food. This oxygen is essential for sustaining life on Earth.
Photosynthesis
The oxygen in Earth's atmosphere originally comes from the process of photosynthesis carried out by early photosynthetic organisms like cyanobacteria, which released oxygen as a byproduct. Over time, the accumulation of oxygen led to the development of an oxygen-rich atmosphere.
The abundance of oxygen in Earth's atmosphere is primarily due to photosynthesis, a process carried out by plants and algae that produces oxygen as a byproduct. Without photosynthesis, oxygen levels in the atmosphere would decrease over time due to various processes that consume oxygen.
The Earth is surrounded by an atmosphere composed of gases like nitrogen, oxygen, and carbon dioxide. This atmosphere protects the Earth from harmful radiation, regulates temperature, and provides the air we breathe.

The process that produces most of the oxygen in Earths atmosphere is photosynthesis. Plants use this process to create food.
Oxygen or O2Oxygen is produced by the process of photosynthesis.

The process responsible for the creation of oxygen in Earth's atmosphere is photosynthesis, which occurs in plants, algae, and cyanobacteria. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into glucose and oxygen. This process has been essential in shaping Earth's atmosphere and maintaining a stable environment for life.
Trees and plants, in the process of photosynthesis, are continually replenishing oxygen into the air.

The Earth is surrounded by an atmosphere composed of gases like nitrogen, oxygen, and carbon dioxide. This atmosphere protects the Earth from harmful radiation, regulates temperature, and provides the air we breathe.
Oxygen is produced through photosynthesis, a process where plants, algae, and some bacteria use sunlight to convert carbon dioxide and water into oxygen and glucose. This process is essential for maintaining the balance of oxygen in Earth's atmosphere.
Cyanobacteria added oxygen to the atmosphere through the process of photosynthesis, fundamentally changing the composition of Earth's atmosphere and enabling the evolution of aerobic organisms.
