Detailed explanation-1: -The Earths producer organisms are primarily its green terrestrial plants and the algae in the oceans. These plants use the carbon from carbon dioxide to create sugar molecules through the process of photosynthesis.

Detailed explanation-2: -Answer and Explanation: The role of producers in the carbon cycle is to serve as carbon sinks. A carbon sink is a reservoir that stores carbon for an indefinite period of time. This helps to reduce the levels of carbon dioxide that are present in the atmosphere.

Detailed explanation-3: -Carbon storage and exchange 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-4: -Photosynthesis and cellular respiration are the main parts of the carbon cycle. Producers use carbon dioxide to make food in photosynthesis. Some of the carbon dioxide is returned to the atmosphere when this food is used for energy during cellular respiration. The rest is stored in the producer’s body as sugar.

Detailed explanation-5: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
