General Overview "Major misconception: Many students believe that the fish 'breathe' by separating out the oxygen from water. Net productivity is the difference between gross productivity and the energy used by the organisms in respiration. Gross productivity: the entire photosynthetic production of organic compounds in … The first 3 pages come from the Monterey Bay Aquarium’s PDF. By subtracting the initial amount of oxygen from the final amount of oxygen. potentially available to consumers (herbivores) Not all of the GPP goes into making biomass (growth and reproduction) Some productivity is used in the autotroph’s own life processes (respiration) and this energy is ultimately lostas heat. ENG-1.A.5 primary productivity, continued gross primary productivity (GPP) is total production of chemical energy produced by autotrophs producers use some of the biomass they produce to stay alive, grow, etc., so not all of it is available to higher trophic levels the amount available to higher levels is called net primary productivity (NPP) NPP = GPP R (where R means respiration: plants own energy needs) How is this measured in an aquatic environment? Depths of 0 meters to 20 meters will have an even higher rate of productivity. Primary production is the production of chemical energy in organic compounds by living organisms.The main source of this energy is sunlight but a minute fraction of primary production is driven by lithotrophic organisms using the chemical energy of inorganic molecules.. Students in APES (AP Environmental Science) need to know how to do math by hand without a calculator. The average gross primary productivity of a coral reef system is 4200 (g C m-2 yr-1).

Gross primary productivity (GPP) is a measure of the total amount of organic energy converted from the sunlight that the producers of an area receive. In an experiment, net primary productivity was measured, in the early spring, for water samples taken from different depths of a freshwater pond in a temperate deciduous forest. d. Describe how the relationship between net primary productivity and depth would be expected to differ if new data were collected in mid-summer from the same pond. c. Net productivity: Resulting amount of the organic compounds in the end after some of it has been used. Explain the data presented by the graph, including a description of the relative rates of metabolic processes occurring at different depths of the pond. primary productivity from which the gross productivity can be calculated. • Not all the plots manipulated in the clipping part of the experiment will pro-vide data that will be needed to do calculations. a. The last page has questions that I made that correspond to various topics in the APES CED. ENG-1.A.4 Productivity is measured in units of energy per unit area per unit time (e.g., kcal/m2/yr). The relationship of primary productivity and depth would be that, lower depth will have at least no increase or decrease of productivity. Productivity: Define each of these terms in your own words. Express your answer in mg fixed carbon/L/day to the nearest hundredth. 1: What is primary productivity? Producers are the plants that can photosynthesize. The students should recognize this as they began to perform the calculations. The Living World NGSS: LS2.A. When the depth of water reached around 30 and up, there was no primary productivity. Coral reefs have some of the highest productivity rates in the world because of their abundance of life. Okay, so I know that net primary production (NPP) is the difference between gross primary production (from photosynthesis) minus Autotrophic respiration (Ra): … When the water in the pond was around 25 meters, the primary productivity rate stayed constant. b. Productivity stands for the total increase in the mass (phytomass). Describe a method to determine net and gross primary productivity in a freshwater pond over a 24-hour period.
