DENDROLOGY

Detailed explanation-1: -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-2: -During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel-glucose and other sugars-for building plant structures. This process forms the foundation of the fast (biological) carbon cycle.

Detailed explanation-3: -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-4: -Plants and animals are linked to each other through the carbon dioxide and oxygen cycle. Plants produce oxygen, a gas that animals and other living things need. Animals and other living things produce carbon dioxide, a gas that plants need to make their own food.

Detailed explanation-5: -The Oxygen-Carbon Dioxide Cycle During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant’s leaves. Oxygen moves out of the plant leaf through these same openings.
