The two main biological processes in the carbon cycle are photosynthesis (which absorbs carbon) and cellular respiration (which moves it back to the atmosphere as carbon dioxide).
Photosynthesis and cellular respiration are two major biological processes involved in the carbon cycle. During photosynthesis, plants take in carbon dioxide from the atmosphere and convert it into glucose, releasing oxygen as a byproduct. Conversely, during cellular respiration, organisms break down glucose to release energy, producing carbon dioxide as a byproduct.
Photosynthesis drives the carbon cycle, combining carbon dioxide and water to produce glucose and oxygen. Respiration drives the oxygen cycle, breaking down glucose to release energy and produce carbon dioxide and water.
Forests and oceans are natural carbon sinks that remove carbon dioxide from the air through the process of photosynthesis and ocean uptake. Trees absorb carbon dioxide during photosynthesis, while oceans absorb carbon dioxide through chemical and biological processes.
Photosynthesis and cellular respiration are the two cellular processes involved in the oxygen-carbon cycle. In photosynthesis, plants take in carbon dioxide and release oxygen, while in cellular respiration, organisms take in oxygen and release carbon dioxide. These processes are interrelated and essential for balancing oxygen and carbon dioxide levels in the atmosphere.
Photosynthesis by plants and other organisms is responsible for producing oxygen, while respiration by animals and other organisms uses oxygen and releases carbon dioxide. These two processes work together in the oxygen cycle to maintain a balance of oxygen in the atmosphere.

The two biological processes most directly dependent on the availability of air are respiration and photosynthesis. Respiration, carried out by animals and many microorganisms, requires oxygen from the air to produce energy by metabolizing food. Photosynthesis, conducted by plants and certain bacteria, relies on carbon dioxide from the air to convert light energy into chemical energy, ultimately producing oxygen as a byproduct.
Many molecules contain carbon atoms, but a common pair includes carbon dioxide (CO₂) and glucose (C₆H₁₂O₆). Carbon dioxide consists of one carbon atom bonded to two oxygen atoms, while glucose is a simple sugar composed of six carbon atoms along with hydrogen and oxygen. Both molecules are essential in biological and environmental processes.

Carbon is essential for life as it forms the backbone of organic molecules, including proteins, carbohydrates, lipids, and nucleic acids, which are crucial for biological processes. Additionally, carbon plays a significant role in regulating Earth's climate through the carbon cycle, where it moves between the atmosphere, oceans, and terrestrial systems, influencing global temperatures and weather patterns.
