A producer.
Photosynthetic organisms is the word. we use that name.
I think that'd be food chain or feeding chain (same thing different names).
Photosynthetic organisms basically just use water, carbon dioxide, and sunlight to make their own food, hence the name photosynthetic, photo meaning light and synthetic meaning the forming or building of more complex substances or compounds from elements or simplier compounds.
There are various words to use: Phototrophs - photosynthetic organisms that use sunlight to make food. Autotrophs - organisms (including phototrophs) that make their own food and don't have to chase it down or catch it like animals (heterotrophs) do. Producers - the energy producers (capturers) in a food chain. Plants are the producers of terrestrial food chains. They are autotrophs in that they can make their own food. They are phototrophs in that they use light to carry out the reactions to make that food (photosynthesis).
Plants produce their own food using 'photosynthesis'.
The first two organisms in a food chain are usually the primary producers such as the plants and the herbivores at the second level.
Which organisms are usually the first step in a food chain
Organisms that can create their own food but do not produce seeds or spores are green algae and cyanobacteria. They use photosynthesis to generate their own food from sunlight, carbon dioxide, and water.
The organism that eats the producer in a food chain is known as a primary consumer or herbivore. These organisms feed directly on plants or algae for energy.
The name for protists that live in water is plankton. They are microscopic organisms that form the base of the aquatic food chain.
Well I would say humans since we have no natural predators but for the second organism, I would put something that is at the top of its food chain like and eagle, lion,bear etc.(that is, if you dont include humans as a predator)
