Chapter 37: Communities And Ecosystems Already Passed

Define a biological community. Explain why the study of community ecology is important. {Ans: A biological community is in assemblage of all the population of organisms living close enough together for potential interaction. The study of community ecology is important because there is a conservation of the endangered species, management of wildlife, game, and fish, control of disease, and controlling species consumption at culture.}Identify and compare the trophic levels of terrestrial and aquatic food chains. {Ans: terrestrial: plants are a main part of photosynthesis. aquatic: producers are photosynthetic protists and Cyanobacteria.}Explain how hippos contribute to the ecological communities in which they live. {Ans: hippos eat approximately 100 pounds of plants per day and excrete 40 pounds of dung per day. The complex organic molecules that are in the dung of hippos support plant growth and provides food for fish that feed off of the nutritional values of the dung.}Explain how food chains interconnect to form food webs. {Ans: food chains simply show the flow of energy from the primary consumers up through all of the different levels of consumers. Food webs are built off of these food chains to show more realistic flow of energy.}Define a
