Chesapeake Bay Food Webs and Eutrophication1.Examine the food web before humans lived in the Chesapeake.Notice which speciesgroups are abundant (dark circles) and which species groups are rare (light circles).Color orcheck the squares on the chart below to indicate which species groups were rare or abundant.2.Are most species abundant or rare? Which species groups are rare?3. The species groups in the chart above and are organized by trophic level.Write the nameof the trophic group for groups A, B, C, D, and E.The trophic groups found in this ecosystemare decomposers, producers, consumers, secondary consumers, and top predators. Include abrief explanation of how each group interacts with other trophic levels.A.B.C.D.E.4.A.How is it possible that the worms/amphipods are considered part of two groups?5. What is group F? What is the role of detritus in the food web?6. List the number of strong and weak interactions for each of the species groups listed at the top of this chart.Count the number of strong and weak connections (arrows going to or from a species group) to complete thechart below:ConnectionSea Floor PlantsPredatory FishGrazing FishFloating AlgaeStrong:Weak:Total:Strong:Weak:Total:Strong:Weak:Total:Strong:Weak:Total:Strong:Weak:Total:7.The producers can be organized based on where they are found in the water. Some floatand some grow from the seabed. Which producers float and which producers grow from thesea bottom?8. In this ecosystem, which type of producers are more abundant, the producers that float orthe producers that grow from the sea bottom?
9.Find and write out a six -step food chain:10. Compare this food chain to a food chain that you find on land. How do they compare in
