Detailed explanation-1: -Plants are called producers. This is because they produce their own food! They do this by using light energy from the Sun, carbon dioxide from the air and water from the soil to produce food-in the form of glucouse/sugar. The process is called photosynthesis.

Detailed explanation-2: -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-3: -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-4: -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-5: -Carbon is an element that is essential to all life on Earth. Carbon makes up the fats and carbohydrates of our food and is part of the molecules, like DNA and protein, that make up our bodies.
