MAKE CONNECTIONS Use the second law of thermodynamics to explain why an ecosystem’s energy supply mustbe continually replenished (see Concept 8.1)
please draw!
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.
MAKE CONNECTIONS As noted in Figure 52.15, theaddition of nutrients to a lake can cause an algal bloom.When these algae die, complex molecules in their bodiesare broken down by decomposers using aerobic respiration. Explain why this would reduce the lake’s oxygenlevels (see Concept 9.1)

However, waterlogging in the soil of some moisttropical forests results over time in a buildup of organicmatter called “peat.” In a short essay (100–150 words), discussthe relationship of net primary production, net ecosystemproduction, and decomposition for such an ecosystem. AreNPP and NEP likely to be positive? What do you think wouldhappen to NEP if a landowner drained the water from atropical peatland, exposing the organic matter to air?arrow_forward
