Document Summary

Photosynthesis (differences and different types of photosynthesis, what"s more important is the overall details) Essential nutrients that organisms in general need to live: h,c,n,o,p. Animals: 5x amount of n that plants have. Autotroph use inorganic sources of carbon and energy. Heterotroph use organic molecules as sources of carbon and energy [eat food] Measured as photon flux density (pfd) ultraviolet wavelengths are so energy rich that they can fry enzymes in plants during photosynthesis therefore, plants use wave lengths in the middle of the spectrum. There is light penetration in the aquatic environment, it varies in wave length, the zone where light penetrates is called the euphotic zone. Less algae and less kelp the deeper you go. [fig7. 4] light cycle and dark cycle light cycle: uses solar light energy to synthesize chemical energy (atp, Nadph) electron donors for calvin cycle provide energy to turn acids into sugars. Calvin cycle (dark cycle): photosynthesis is often called carbon fixation.
