Photosynthesis (/ ˌ f oʊ t ə ˈ s ɪ n θ ə s ɪ s / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C. [10] By photosynthesis , green plants convert solar energy into chemically stored energy, which produces food, wood and the biomass from which fossil fuels are derived.
Heterotrophic nutrition is a mode of nutrition in which organisms depend upon other organisms for food to survive. They can't make their own food like Green plants. Heterotrophic organisms have to take in all the organic substances they need to survive. All animals, certain types of fungi, and non-photosynthesizing plants are heterotrophic.
[5] [6] Sunlight is the primary energy source, with its radiant energy being transduced to chemical energy stored in bonds, typically by reducing protons to hydrogen, or carbon dioxide to organic compounds. A solar fuel can be produced and stored for later use, when sunlight is not available, making it an alternative to fossil fuels and ...
The U.S. Food and Drug Administration (FDA) announced a new definition of “healthy” food for the first time in 30 years. The new definition will apply to manufacturers who want to call their ...
Photosynthesis is the main means by which plants, algae and many bacteria produce organic compounds and oxygen from carbon dioxide and water (green arrow). An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds , which can be used by other organisms .
