what organisms are classified as autotrophs
Any plant with green leaves is classified as an autotroph. The definition covers trees, mosses and flowering plants, to name a few. Most plants use photosynthesis to produce food in the form of sugar. Plants are not the only organisms classified as autotrophs, although they are one of the most well-known examples. Phytoplankton, algae and some types of bacteria are also able to make their own food. Some of these organisms use chemosynthesis instead of photosynthesis.
