Which trophic level in an aquatic ecosystem would contain the greatest amount of usable energy?
Primary consumers located 150 meters below sea level.
Primary producers located 80 meters below sea level.
Primary producers located 45 meters below sea level.
Primary consumers located 40 meters below sea level.
EcosystemA hasprimary production of 1000 g C /m2/yr and ecological efficiency of 10%. Ecosystem B has primary production of 300 g C /m2/yr and an ecological efficiency of 25%.
a.Which ecosystem will have more production at thesecondary consumer (carnivore) trophic level?
b.Which ecosystem is more likely to support an endothermic primary consumer (herbivore)?
c.If atrophic level requires at least 1 gC/m2/yr in order to exist, how many trophic levels can each of these ecosystems support?d.Given your answer to part c, which do you thinkhas a larger impact on the energy available at upper trophic levels: primary productivity or efficiency of energy movement across trophic levels?
