Photosynthesis - Education | National Geographic Society
2024年6月21日 · During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.
Photosynthesis - Education | National Geographic Society
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.
Chlorophyll - Education | National Geographic Society
2023年10月31日 · Chlorophyll is a key component in the process of photosynthesis, which sustains plant life and produces oxygen for the entire planet. Although microscopic in size, chloroplasts like these have a big role to play in the health of the planet.

2023年10月19日 · Learn about the process that plants, algae, and some bacteria use to make their own food and the oxygen we breathe.
Sweet Secret - Education
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.
Heterotrophs - Education | National Geographic Society
2023年10月19日 · Heterotrophs benefit from photosynthesis in a variety of ways. They depend on the process for oxygen, which is produced as a byproduct during photosynthesis. Moreover, photosynthesis sustains the autotrophs that heterotrophs depend on to survive.
The Carbon Cycle - Education
2023年10月19日 · For example, some carbon in the atmosphere might be captured by plants to make food during photosynthesis. This carbon can then be ingested and stored in animals that eat the plants. When the animals die, they decompose, and their remains become sediment, trapping the stored carbon in layers that eventually turn into rock or minerals.
Autotroph - Education | National Geographic Society
2024年11月18日 · 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 …

Plankton - Education | National Geographic Society
2023年10月19日 · Phytoplankton make their energy through photosynthesis, the process of using chlorophyll and sunlight to create energy. Like other plants, phyto plankton take in carbon dioxide and release oxygen. Phyto plankton account for about half of the photosynthesis on the planet, making them one of the world’s most important producers of oxygen.
