This process results by the actions of photosynthetic Enzymes - the Process is termed Photosynthesis. Performed by the Smallest Of All Creatures - Phytoplankton - they are the Base of the Food Chain. Our position on the Top of the Food Chain, being based solely upon the Healthy Existence of PhytoPlankton, is indeed Precarious.
Old Material: Seventy percent of Our Earths Oxygen is 'derived' from Plankton.

∙ 12y agoPhototrophs are the organisms that carry out photosynthesis to acquire energy. They use the energy from sunlight to convert carbon dioxide and water into organic material to be utilized in cellular functions such as biosynthesis and respiration.
Most phototrophs are autotrophs, also known as photoautotrophs, and can fix carbon. They can be contrasted with chemoautotrophs that obtain their energy by the oxidation of electron donors in their environments. Photoheterotrophs produce ATP through photophosphorylation but use organic compounds to build structures. Some phototrophs are organotrophs, also known as photo-organotrophs.
In an ecological context, phototrophs provide nutrition for all other forms of life (besides other autotrophs such as chemotrophs). In terrestrial environments, plants are the predominant variety, while aquatic environments include a range of phototrophic organisms such as algae (e.g., kelp), other protists (such as euglena), phytoplankton, and bacteria (such as cyanobacteria).
One product of this process is starch, which is a storage or reserve form of carbon, which can be used when light conditions are too poor to satisfy the immediate needs of the organism. Photosynthetic bacteria have a substance called bacteriochlorophyll, live in lakes and pools, and use the hydrogen from hydrogen sulfide instead of from water, for the chemical process. (The bacteriochlorophyll pigment absorbs light in the extreme UV and infra-red parts of the spectrum that is outside the range used by normal chlorophyll). Cyanobacteria live in fresh water, seas, soil, and lichen, and use a plant-like photosynthesis.
A photolithotrophic autotroph is an autotrophic organism that uses light energy, and an inorganic electron donor (e.g., H2O, H2, H2S), and CO2 as its carbon source. Examples include plants.

What turns sunlight into energy?
solar panels in technological terms. It takes in light energy from the sun and converts it into electrical energy. Chlorophyll in natural terms, found in plants. Usually, photoautotrophs that make their own food from the energy they get from light energy.
Organisms that capture light energy from the sun and transform it into food are called?
An autotroph is an organism that is able to produce its own food. In contrast, a heterotroph must consume other organisms for energy.
How do geysers make energy?
Geysers do not make energy.
Explain how most energy used on earth can be traced back to the sun?
Photoautotrophs (mostly) are the only organisms which can produce their own food using the energy from the Sun. All other organisms either have to eat plants (primary consumers) or eat animals that eat plants (secondary consumers). There are relatively few tertiary consumers.
What energy sources make up the world's energy supply?
Oil and coal make up the world's energy supply.
Autotrophs that utilize light as their energy source are?
Photoautotrophs use light as the energy source for producing proteins, lipids and other organic substances. Examples of photoautotrophs are plants.
What reactants do photoautotrophs need for photosynthesis?
Photoautotrophs need water, carbon dioxide, and light energy in order to power photosynthesis.
These use light energy from the sun to produce food?
Photoautotrophs.
What food making process is used by photoautotrophs?
Photoautotrophs use sunlight to make their food also called photosythesis
How do organisms make their own food?
Photoautotrophs
What organisms that perform photosynthesis to make their own food?
All plants, some protists and some bacteria can preform photosynthesis.
What turns sunlight into energy?
solar panels in technological terms. It takes in light energy from the sun and converts it into electrical energy. Chlorophyll in natural terms, found in plants. Usually, photoautotrophs that make their own food from the energy they get from light energy.
How do producer organisms make their own food?
Photoautotrophs
What were the first types of cells able to make their own food?
Photoautotrophs
Organisms that can exist with light as an energy source and an inorganic form of carbon and other raw materials?
photoautotrophs
What is the main pigment of photoautotrophs?
Photoautotrophs are photosynthetic organisms.They mainly have chlorophyll.
How are photoautotrophs and photoheterotrophs?
Photoautotrophs: Bacteria that use sunlight as their energy source and carbon dioxide (as part of photosynthesis) as their carbon source. These bacteria thus obtain all their nourishment through photosynthesis Photoheterotrophs: Bacteria that use sunlight as their energy source and organic compounds from the environment as their carbon source.
