Living thing that breaks down other organisms into chemicals?
Producers are organisms that can create their own food from raw chemicals and energy from sunlight. (Plants) Consumers are organisms that can't make their own food so they kill and eat other living things to live. (Cows and Tigers) Decomposers are organisms that eat the stuff that consumers leave behind, they rot things away and release the chemicals for producers to re use. (Mushrooms and bacteria).
While other living organisms reproduce and live by themselves, viruses do the same only after entering the body of other living organisms.They do so by using the cellular machinary of the host.In other words, they are nonliving as long as they are existing own their own, and shows signs of life only when they enter living organisms.
No, autotrophs are organisms which can create their own food. An example of an autotroph is a plant. Plants produce food by the means of photosynthesis. Plants are at the bottom of trophic levels, and are food for all other organisms. Heterotrophs are organisms which do consume other organisms for food.
