By transforming light energy into chemical energy, photosynthesis provides the energy used by organisms, whether those organisms are plants, grasshoppers, wolves, or fungi. The only exceptions are found in very rare and isolated ecosystems, such as near deep sea hydrothermal vents where organisms get energy that originally came from minerals, not the sun.
The efficiency of uncultivated plant life is only about 0.2%. In sugar cane, which is one of the most efficient plants, about 8% of the light absorbed by the plant is preserved as chemical energy. Many plants, especially those that originate in the temperate zones such as most of the United States, undergo a process called photorespiration.

Oct 26, 2024 · Photosynthesis is a fundamental biological process that enables plants to convert light energy into chemical energy, sustaining life on Earth. This mechanism not only fuels plant growth but also provides the oxygen and organic compounds necessary for other organisms.
Jun 21, 2024 · Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores. The process. 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 ...

Fungi and bacteria are decomposers, and worms are detritivores (not shown). During each energy transfer, some of the energy in the system is lost as heat. Consumers can be classified based on whether they eat animal or plant material (figure \(\PageIndex{5}\)). Consumers that feed exclusively on animals are called carnivores. Lions, tigers ...
