DENDROLOGY

Detailed explanation-1: -Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

Detailed explanation-2: -Plants produce sugar and oxygen in a process called photosynthesis, by using sunlight, water, and carbon dioxide. This is an important process on Earth, since it removes carbon dioxide from the air and provides food for us. Photosynthesis happens in small compartments within the plant cells, called chloroplasts.

Detailed explanation-3: -It uses chemical energy stored in ATP and NADPH (from the light reactions) and carbon dioxide from the air to produce glucose, the molecule that virtually all organisms use for food.
