Document Summary

Ecological significance: autotrophs sustain themselves without eating anything derived from other organisms. (like photosynthesis autotrophs- prokaryotes (this is a connection) They can fix their own carbon- take carbon gas and turn it into sugar. single -celled organism that photosynthesis. Autotrophs= producers, they produce their food by absorbing energy and changing it to chemical energy: heterotrophs obtain their organic material from other organisms. Heterotrophs= humans, humans need to get carbon from something else. Need to consume, need to get carbon from something else. Shorter wavelength- more energy/photon longer wavelength- less energy/ photon: most biological processes use visible light because enough energy to be. Return to lower e orbital (ground state) useful, but do not enough to be destructive. They are the perfect amount: when a molecule absorbs a photon of light e , an e- becomes energized shifts from lower e orbital to higher e. Leave atom and be captured by an e- acceptor: acceptor is then reduced.
