$\bold{\underline{\underline{Hello\:Brainly\:User!}}}$

☯ A N S W E R :-

• The oxygen cycle is the biogeochemical transitions of oxygen atoms between different oxidation states in ions, oxides, and molecules through redox reactions within and between the spheres of the planet Earth.

• The oxygen cycle is the cycle that helps move oxygen through the three main regions of the Earth, the Atmosphere, the Biosphere, and the Lithosphere.

• The Oxygen cycle is how oxygen is fixed for freed in each of these major regions. In the atmosphere Oxygen is freed by the process called photolysis.

❇ Let's go deep into into the topic!

↪How often does oxygen cycle through the atmosphere?

• About every 1000 years oxygen cycle through the atmosphere.

↪How is oxygen cycled through the atmosphere?

• The entire cycle can be summarized as, the oxygen cycle begins with the process of photosynthesis in the presence of sunlight, releases oxygen back into the atmosphere.

• which humans and animals breathe in oxygen and breathe out carbon dioxide, and again linking back to the plants.

↪Why oxygen is so important?

• Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things.

• We humans, along with many other creatures, need oxygen in the air we breathe to stay alive.

• Oxygen is generated during photosynthesis by plants and many types of microbes.

Answer 2

The oxygen cycle describes the various forms in which oxygen is found and how it moves through different reservoirs on Earth. It is one of the biogeochemical cycles.

There are three major reservoirs of oxygen: the atmosphere, biosphere, and lithosphere. Some people also consider the hydrosphere, a subdivision of the biosphere, to be the fourth reservoir.

The biosphere includes all living and nonlivingcomponents on Earth. In the biosphere, oxygen is mostly found in organic molecules, liquid water, and molecules dissolved in water, such as free oxygen and carbonic acids.

In the atmosphere, the oxygen is mostly found as free O2 molecules released via photosynthesis, but also exists as ozone (O3), carbon dioxide (CO2), water vapor (H2O), and sulfur or nitrogen oxides.

The lithosphere includes the Earth's crust and mantle, and it's the largest oxygen reservoir. Large amounts of oxygen are stored in silica (SiO2) and other oxide minerals.

Oxygen moves into the atmosphere via the process of photosynthesis and photolysis. Oxygen moves to the biosphere via respiration, decay, and mineral extraction from rock. It moves into the lithosphere via surface reactions, chemical weathering, and calcium carbonate formation which leads to sedimentary rock formation.
