Document Summary

Photosynthesis is the process that converts light energy into chemical energy: directly or indirectly, photosynthesis nourishes virtually the entire living world o. Carbon fixation catalyzed by rubisco: output of sucrose. Autotrophs are organisms that sustain themselves without consuming anything derived from other organisms o. Produce organic molecules from co2 and other inorganic molecules. Biosphere- the sum of all the living ecosystems on planet earth: almost all plants are photoautotrophs- organisms that use the energy of sunlight to make organic molecules from water and co2 via the process of photosynthesis. Photosynthesis occurs in plants, algae, and certain protists (unicellular eukaryotes) and some prokaryotes o. These organisms feed not only themselves, but also virtually the entire living world: not all plants carry out photosynthesis. Heterotrophs obtain their organic material from other organisms: consumers of the biosphere o. Completely dependent on autotrophs for food and oxygen. 6co2 + 12h2o + photons c6h12o6 + 6o2 + 6h2o.
