EVERYDAY SCIENCE

Detailed explanation-1: -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-2: -Plants constantly exchange carbon with the atmosphere. Plants absorb carbon dioxide during photosynthesis and much of this carbon dioxide is then stored in roots, permafrost, grasslands, and forests. Plants and the soil then release carbon dioxide when they decay.

Detailed explanation-3: -During the spring and summer, trees and plants absorb carbon when they undergo photosynthesis, reducing the amount of carbon in the atmosphere. During the fall and winter, they decay, releasing carbon back into the atmosphere.

Detailed explanation-4: -Living organisms release carbon dioxide as a byproduct of cellular respiration. Photosynthesis removes carbon dioxide from the atmosphere and uses it to make organic compounds.

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.
