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?
