Mica Piro Chapter 10: Photosynthesis The Process That Feeds the Biosphere The conversion of light energy from the sun to chemical energy stored as sugar is called photosynthesis (occurs in algae, certain other unicellular eukaryotes, and some prokaryotes) Nourishes almost the entire living world directly or indirectly Organism acquires the organic compounds it uses for energy and carbon skeletons by one of 2 major modes: autotrophic nutrition or heterotrophic nutrition Autotrophs (?self-feeders?) sustain themselves without eating anything derived from other living beings Produce their organic molecules from CO2 and other inorganic raw materials obtained from the environment
