LIFE SCIENCE

Detailed explanation-1: -Plants synthesize glucose using carbon dioxide and water by the process of photosynthesis, and the glucose, in turn, is used for the energy requirements of the plant. The excess synthesized glucose is often stored as starch that is broken down by other organisms that feed on plants.

Detailed explanation-2: -This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules. Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight.

Detailed explanation-3: -Plants form glucose by photosynthesis and animals get glucose by breaking down the food they eat. During cellular respiration, glucose combines with oxygen to release energy and to form carbon dioxide and water. Most of the carbon dioxide in animals is released into the air when the animal breathes.
