Detailed explanation-1: -They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.

Detailed explanation-2: -The sun keeps the carbon cycle working by providing light energy. This light energy is used to carry out a process called photosynthesis by organisms that are known as producers. This process creates organic matter from carbon dioxide and water. Photosynthesis thus helps maintain the activity of carbon sinks.

Detailed explanation-3: -As plants photosynthesize, they absorb carbon dioxide from the atmosphere.

Detailed explanation-4: -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.

Detailed explanation-5: -In a process called photosynthesis, plants use the Sun’s energy to pull carbon dioxide (CO2) from the air, and use the carbon to build stems, roots and leaves. That’s important, because in the atmosphere, carbon dioxide acts as a heat-trapping gas that warms the Earth.
