DENDROLOGY

Detailed explanation-1: -Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy.

Detailed explanation-2: -Leaves make their own food by the process of photosynthesis. During photosynthesis, plants use sunlight, water, and a gas in the air called carbon dioxide. Plants use these materials to make sugar, which is a source of food and energy for plants.

Detailed explanation-3: -Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.

Detailed explanation-4: -Pine trees go about their essential work converting energy from the sun into the fuel they need to grow and survive – photosynthesis, in other words – via green leaves of a distinctive form shared by many other conifers: needles.

Detailed explanation-5: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
