AP BIOLOGY

Detailed explanation-1: -It is the source of energy and food for all organisms. It releases oxygen into the environment which is utilised by organisms.

Detailed explanation-2: -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. Without this process, life on Earth as we know it would not be possible.

Detailed explanation-3: -It ensures that all living species have access to oxygen in the atmosphere. It keeps the ecosystem’s oxygen and carbon dioxide levels in check. Plants are the source of fossil fuels. Energy is locked in fuel as a result of photosynthesis in the sun.

Detailed explanation-4: -The Sun! The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.

Detailed explanation-5: -Factors that influence the rate of photosynthesis The amount of light, the carbon dioxide supply, temperature, water supply, and the availability of minerals are the most important environmental factors that affect the rate of photosynthesis in land plants.
