Detailed explanation-1: -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.

Detailed explanation-2: -To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food.

Detailed explanation-3: -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-4: -Answer and Explanation: Producers (including plants, some protists, and bacteria) synthesize food by converting carbon dioxide and water into sugars using energy from the sun or inorganic sources. During the process of photosynthesis, six carbon dioxide molecules are combined with six water molecules.

Detailed explanation-5: -It is not completely true that carbon dioxide is a waste product in plants because plants can use carbon dioxide as a reactant in photosynthesis to produce glucose.
