Document Summary
Primary productivity conversion of inorganic compounds into organic compounds. Gross primary productivity amount of chemical energy produced in a given time. Net primary productivity amount of chemical energy - chemical energy used by primary producers: what"s left for the animals. Aquatic biomes: water is a polar molecule, cohesion is water attracted to itself, adhesion is water attracted to other things, water is most dense at 4 degrees centigrade. Ocean upwelling as surface water moves away from coast, it gets replaced by bottom water. Lake turnover: during spring and fall, the oxygen rich surface water and nutrient rich bottom water switch due to the water at the surface being most dense at 4 degrees. Water depth & light: light only hits 200m down, this results in photosynthesis to only occur there. Estuaries: where rivers meet oceans, shallow, nutrients rich, high npp.
