DENDROLOGY

Detailed explanation-1: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Detailed explanation-2: -Sunlight, chlorophyll, carbon dioxide, water and minerals are raw materials essential for photosynthesis.

Detailed explanation-3: -Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Detailed explanation-4: -All plants with green leaves, from the tiniest mosses to towering fir trees, synthesize, or create, their own food through photosynthesis. Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis.

Detailed explanation-5: -This process is called photosynthesis. They capture the energy from the sun and use it to convert water and carbon dioxide into carbohydrates (sugars). Plants then use the carbohydrates to grow. Plants (and a few other lifeforms) release oxygen during photosynthesis.
