What does air do for an ecosystem?

How do you make an oxygen cycle?
Photosynthesis is a biological process by which all green plants synthesize their food in the presence of sunlight. During photosynthesis, plants use sunlight, water, carbon dioxide to create energy and oxygen gas is liberated as a by-product of this process. Sunlight: Sunlight also produces oxygen.
How is biomass created in an ecosystem?
The biomass in an ecosystem includes the mass of all living and dead organic matter. Production is the incremental increase in biomass produced by organisms over a period of time. Primary production refers to the production of organic matter, such as body tissue, produced mainly by photosynthetic plants.
