Explain how energy flow supports the second law of thermodynamics in an ecosystem.

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.

Thinking Analytically Is phytoplankton productivity highest at the ocean surface? What advantage would optimum productivity at a depth below the surface provide to phytoplankton?

Marine biology question 6) Just before the beginning of the fishing season you capture, tag, and release 4500 adult cod (Gadus morhua) from the Barents Sea. At the end of the season you learn from the United Kingdom Trawler Fleet working these waters that a total 195,500 fish were taken in the season, of which 1,950 fish were found bearing your tag. From these data calculate the “fishing ratio”, also known as the rate of exploitation, of this fishery. What was the size of the cod population actually available to this fishery at the beginning of the season?

Cycles of Matter and Energy Transfer in Ecosystems:Question 1 Which statement is true about photosynthesis? Select one: One of the inputs of photosynthesis is oxygen. O During photosynthesis, energy from the sun is stored in the chemical bonds of a glucose molecule. Photosynthesis happens in the mitochondria. Photosynthesis releases energy to the environment.

Photosynthesis and cellular respiration are related to each other through     the cycling of carbon in various forms as it moves through different living and nonliving systems.     only the breaking down of molecules which support chemicals reactions that occur in living things.     their reliance on processes like fossilization, combustion, feeding, etc. to move chemicals needed to support life.     A and B     A and C
