Solution:

The organisms obtaining energy by chemical reactions independent of light are called chemotrophs. When the reductants are obtained from the environment in an inorganic form, the organisms are chemoautotrophs. When the reductants are organic, the organisms are chemoheterotrophs.
Photoautotrophs make their food by photosynthesis using the energy of the sun. Saprozoic organisms obtain food from dead and decaying matter.
