Autotrophs
autotrophs
Humans are not free-living organisms as they parasitically derive nutrition from the suffering of others.
Actually they are not autotrophs,they are phototrophs.Autotrophs are organisms who use CO2 as Carbon sourse.
There is a certain hierarchy in science. The most basic description of how the universe functions is found in the field of physics. From the principles of physics, derive the principles of chemistry. From the principles of chemistry, derive the principles of biology. And from the principles of biology, derive all the functions of an organism.
Organic compounds produced outside themselves.
Photosynthesis needs light to happen, and that usually means sunlight, but it is also possible to grow plants with artificial lighting, which is also a suitable source of energy for photosynthesis.
Autotrophs
Producers obtain energy through photosynthesis, where they convert sunlight into chemical energy. They can also derive energy from chemosynthesis by utilizing chemical reactions with inorganic compounds.
Fish cannot be producers because they do not derive their energy from photo- or chemosynthesis.
So-called 'primary producers', organisms that produce biomass from simple chemical compounds and an external energy source. Plants are primary producers: they produce plant biomass from CO2 and water, using the sunlight as a source of energy. In the ocean, phytoplankton is responsible for most of the primary production. Some organisms use energy sources other than light to produce biomass. Some bacteria, for instance, derive their energy from the oxidation of inorganic chemical compounds (e.g. H2S). In the deep sea, whole communities are supported by this kind of chemosynthesis.

The vast majority of organisms that are designated as producers (generally plants) derive their energy from the sun through photosynthesis. Some exceptions to this are called extremophiles, which gain energy through chemosynthesis (such as bacteria around deep ocean vents).

Heterotrophs. These organisms derive their food from autotrophs,that is, the plants. They include- Carnivores, herbivores, omnivores, scavengers, decomposers.

Organic molecules form the structure of all living organisms and derive energy from the organism's environment.
