Photosynthetic Organisms

Organisms capable of photosynthesis, a process that converts light energy into chemical energy, sustaining the food chain.

Autotroph

An organism that synthesizes complex organic compounds from simple inorganic raw materials; also called producer or primary producer. Compare with heterotroph. See chemoautotroph and photoautotroph.

Saprotroph

A saprotroph is an organism that feeds on or derives nourishment from decaying organic matter, essential for nutrient cycling in ecosystems.
