autotrophs An autotroph (from the Greek autos = self and trophe = nutrition) is an organism that produces organic compounds from carbon dioxide as a carbon source, using either light or reactions of inorganic chemical compounds, as a source of energy. An autotroph is known as a producer in a food chain. Plants and other organisms that carry out photosynthesis are phototrophs (or photoautotrophs). Bacteria that utilize the oxidation of inorganic compounds such as hydrogen sulfide, ammonium or ferrous iron as an energy source are chemoautotrophs. Aloha.

In the vast majority of plants and animals, the body is made up of numerous cells. They are called multicellular organisms. A multicellular organism is actually an aggregation of cells. Here a group of cells functions in a same way to form a tissue or an organ (Example: Xylem vessels, cork cells, cells in the skin).Multicellular organisms have a great capacity to survive than unicellular organisms.n some lower forms of life (Example: Euglena, Amoeba) The body is formed of a single cell; these organism are described as unicellular. In a unicellular organism, all life activities are carried out by itself with its internal structures. The intracellular structures are called the organelles.
