Detailed explanation-1: -Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals.

Detailed explanation-2: -When they’re exposed to light, green plants use carbon dioxide from the atmosphere to manufacture living matter and release oxygen into the air. This process is called photosynthesis. Carbon dioxide is produced through the respiration of animals and plants, which consume oxygen and release carbon dioxide.

Detailed explanation-3: -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.

Detailed explanation-4: -For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.

Detailed explanation-5: -Plants-Plants create the majority of the oxygen we breathe through a process called photosynthesis. In this process plants use carbon dioxide, sunlight, and water to create energy. In the process they also create oxygen which they release into the air.
