DENDROLOGY

Detailed explanation-1: -Plants are called producers because they make – or produce – their own food. Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight.

Detailed explanation-2: -Trees gather light for photosynthesis through their leaves; this process creates “food” for the tree.

Detailed explanation-3: -The leaves have a green pigment called chlorophyll. It helps leaves to capture the energy of the sunlight. This energy is used to synthesize food from carbon dioxide and water. Thus, chlorophyll, sunlight, carbon dioxide and water help to carry out the process of photosynthesis.

Detailed explanation-4: -They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
