Document Summary
Chapter 13 homework: chemosynthesis and photosynthesis are both primary forms of primary productivity. This is the rate at which energy is stored by organisms through the formation of organic matter using energy derived from solar radiation, photosynthesis, or from chemical reactions during chemosynthesis. The organic matter produced by either process can be used as food for other organisms. Chemosynthesis helps support hydrothermal vent bio- communities along oceanic spreading centers: in the open ocean the solar energy extends deeper into the water column, but the concentration of nutrients is low. In coastal regions, light penetration is much less, but the concentration of nutrients is much higher. Coastal waters and upwelling areas are biologically very productive and almost always are yellow-green in color because they contain large amounts of yellow-green microscopic. These material disperse solar radiation so that the wavelengths for greenish or yellowish light are scattered most.
