Question on: SS2 Biology - Nutrient Cycling In Nature

The oxygen cycle involves the production and consumption of oxygen in the environment. Oxygen is primarily produced through photosynthesis by plants, algae, and cyanobacteria. During photosynthesis, these organisms convert carbon dioxide and sunlight into oxygen and glucose. Oxygen is then consumed by organisms through respiration, where it is used in the breakdown of organic molecules to release energy. The cycle is maintained by a balance between oxygen production and consumption by various organisms.
