- In the Chesapeake Bay estuary, the blue crab is an omnivore that eats eelgrass and other primary producers as well as clams. It is also a cannibal. In turn, the crabs are eaten by humans and by the endangered Kemp's Ridley sea turtle. 1) Based on the above information, describe the food web that includes the blue crab. Identify the trophic levels and the organisms that occupy each. Some organisms may occupy more than one trophic level. 2) Assuming that top-down control occurs in this system, describe what would happen to the abundance of eelgrass if humans stopped eating blue crab.arrow_forwardWhich of the following is a component of an ecosystem but not of an ecological community?

- A researcher measures the amount of mercury (a persistant toxic chemical) in the fish of a lake ecosystem. The concentration of mercury is 10 times higher in the tertiary consumer fish species compared to the amount in the primary consumer fish species. A) Explain this result using the term bioaccumulation and biomagnification. B) If a bear eats mainly the tertiary consumer fish from this lake, how would you expect the mercury concentration in the bear to compare to the fish?arrow_forwardWhich of the following statements BEST describes energy transfer in an ecosystem?

If the primary consumer has 175,000 kcal available, the secondary consumer will receive 17,500 kcal from the primary consumer. C. If the primary consumer has 175,000 kcal available, the tertiary consumer will receive 175 kcal from the secondary consumer. D.
