8. For each of the biogeochemical cycles in the table below, list at least three areas on Earth where the chemical elements or compounds are stored (i.e., reservoirs). Biogeochemical cycles Storage pools or reservoirs Water Carbon Nitrogen Phosphorus 9. For the three biogeochemical cycles listed below, choose two reservoirs you have listed in the table from Question #8 and describe how the chemical elements/compounds moves between the two reservoirs. Note, you do not have to describe the complete cycle for each element/compound, simply describe the processes that connect two of the reservoirs that make up the cycle. Water: Carbon: Nitrogen:

1.) Describe a food chain that has at least four different trophic levels. Label the tropic level (Producer, Primary consumer, Secondary Consumer, or Tertiary Consumer), whether the organism is a(n) autotroph or heterotroph, and provide an example of an organism at each tropic level.   2.)Name two biological processes involved in rapid carbon exchange:   3.)Name two geologic processes involved in long-term carbon exchange:

estimate the total primary production in the oceans (in million metric tons carbon) using the following information - 92% of oceans are open ocen with an average productivity of 125 gC/m2/yr - 8% of the oceans are coastal, with an average productivity of 2,000 gC/m2/yr - remember a metric ton is 1,000 Kg

8. Create a food web using the following food chains  Berries to Deer to Black bear Algae to Salmon to Black bear Algae to Squid to Blue shark to Humans    9. Create a Food pyramid using the terms produces and consumers along with organisms from #8. Explain the energy transfer   10. Tom goes to Max's Bistro and orders the Blue shark, which gives him 2 kCal of energy. How much energy, on average, would have been necessary in the algae plants to sustain Tom's meal? Explain how you got your answer.

AP Environmental Science Primary Productivity Problems   Net Primary Productivity efficiency can be calculated for terrestrial producers when values for insolation energy, respiration loss and gross productivity are known. Use the equations below to answer the following problems:   Net Primary Productivity = Gross Productivity – Respiration Loss   Efficiency = .          NPP           . X 100                      Insolation Energy   In a rice paddy in Southeast Asia, the insolation energy is 6,000,000 calories/m2/day. The gross productivity of the rice is 0.012 grams/cm2/day, and the respiration loss is 20 percent. One gram of rice is equivalent to 1000 calories.   Calculate the net primary productivity of the rice.               Find the efficiency of photosynthesis by the rice.   Could you mostly help me set it up and find it? So I can learn how to do it.

21. Decomposers are critical in the nitrogen and phosphorus cycles because they:   are responsible for the fixation of the nutrients into a bioavailable form allow for the cycling of the nutrients within the biosphere are involved in processes that return the nutrients to their major reservoirs More than one of these choices is correct.

Find the Flaw   Biomagnification in how the amount of toxin in an organism will increase as you move up a food chain. For example, a plant might only have a little toxin but an herbivore eats a lot of plants. So, now the herbivore has a medium amount of toxin. A carnivore eats a lot of herbivores and now the carnivore has a high amount of toxin and is sick.   The water cycle has five important processes. Evaporation which is water turning into vapor. Condensation and precipitation refer to water vapor turning into liquid or solid water. Subsurface water flow feeds rivers and streams. Surface runoff is water from precipitation gathering in streams. Streamflow moves water from mountains to oceans. The nitrogen cycle has four steps. Denitrification is where bacteria take nitrogen from the atmosphere and convert it into a form that is usable by other biological systems. Ammonification is where nitrogenous waste is converted into ammonia. Nitrification is where ammonia is converted into…
