Create a model which accurately, in detail, depicts the potential pathways of carbon (biomass) and energy in an ecosystem with at least five trophic levels (don’t forget your decomposers, they can count as one trophic level). Make sure to incorporate the multiple pathways that biomass and energy could take at each trophic level. Lastly, clearly illustrate how carbon and energy flow in this ecosystem. Be sure to include adequate levels of detail for all pathways and differentiate the flow of carbon and energy in your model.

- 4) A chicken farm produces about 800 kJ/m' of potential food energy per year. Assume that a human must consume 2400 kJ per day to survive. Although it is an oversimplication to imply that a person could survive by eating only one type of food, calculate the total area of land needed to support the entire student population of your school (n=1800) for one year on a diet of (a) rice ONLY and (b) chicken ONLY.

Annual net secondary production by the herbivorous insect community was 320.5 g/m/yr. Total net tertiary production by spiders was 22.6 g/m/yr. Calculate the trophic efficiency from the first trophic level to the third trophic level.arrow_forwardNitrogen is often the limiting nutrient (that is, the nutrient in shortest supply relative to demand) across a wide range of ecosystems. This is because: a. nitrogen compounds like ammonia are rapidly stored in rocks and sediments. O b. most nitrogen is in the form of N2, which only specialized bacteria can fix into accessible forms. О с. there is very little nitrogen on Earth, compared with other nutrients. O d. decomposers don't return nitrogen to a usable form.arrow_forward
