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

Without it, they wouldn’t have the food, energy, and nutrients they need to survive. For centuries, scientists knew that plants could turn carbon dioxide and water into sugar (carbohydrates) using light energy—a process called photosynthesis. However, they didn’t know exactly how this was accomplished.
The process in which a tree or other plant makes food is called photosynthesis. During photosynthesis, leaves use energy from sunlight to combine water and carbon dioxide. This reaction, which takes place inside cells called chloroplasts, creates sugar and oxygen. The sugar provides energy so the tree can live.
Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color.
Did you know that most of the oxygen we breathe comes from tiny plants in the ocean? They make it using a process called photosynthesis. National Geographic Explorer and oceanographer Branwen Williams explains how plants use sunlight to feed themselves and give us oxygen.
Carbon is in a constant state of movement from place to place. It is stored in what are known as reservoirs, and it moves between these reservoirs through a variety of processes, including photosynthesis, burning fossil fuels, and simply releasing breath from the lungs.
How do producers work this magic of storing the energy from sunlight in molecules that other organisms can use? They accomplish this feat with a biochemical reaction called photosynthesis. This process uses the energy of sunlight to split water molecules into hydrogen and oxygen.
Photosynthesis is a process that involves making glucose (a sugar) and oxygen from water and . carbon dioxide using energy from sunlight. Autotrophs are able to manufacture energy from the sun, but heterotrophs must rely on other organisms for energy.
