Mоdule 1: Mоvement оf Mаtter аnd Energy, Applicаtion ExamDirections: On a piece of paper answer the following questions. YOU MUST SHOW ALL OF YOUR WORK for the calculations to receive credit. PLEASE CLEARLY LABLE ALL OF THE STEPS in your calculations, so that I can easily follow your calculation process. You will not get credit for your answers if you do not show your workYou have 1 hour to complete these problems, take a picture of your answers and upload your completed assignment to Blackboard.________________________________________________________________Calculation of flow of energy through an aquatic ecosystem:Use the following data to answer the questions below:The amount of solar radiation is 1,200,000 kcal/m2/yrAlgae absorb 1.2% of solar radiation for use in photosynthesis OrganismTrophic (Production) Efficiency% of new biomass consumed (ingested)% of consumed biomass assimilated Algae60%--------------------------------------- Zooplankton50%40%60% Catfish10%40%40% Northern Fish10%40%70%Question 1: Zooplankton are small microscopic aquatic organisms. If zooplankton were the only primary consumer in an aquatic ecosystem, how much new zooplankton biomass could be produced in a year?Food Chain = Algae --> ZooplanktonQuestion 2: If Catfish were the only primary consumer, how much new catfish biomass could be produced in a year?Food Chain = Algae --> CatfishQuestion 3: Northern fish eat catfish. Use your answer for Question 2 to determine how much Northern fish can be produced (in units of kcal/m2/year)?Food Chain = Algae --> Catfish --> NorthernQuestion 4:Using the terms associated with how energy flows through a food chain, explain why each m2 of lake is able to produce more zooplankton or catfish biomass.If eagles (bird, endotherm) were eating the catfish in this ecosystem, would more or less eagle biomass be produced per m2 than northern (fish, ectotherm)? Explain your answer.Follow these directions CAREFULLY to upload your answers: You can now get your phone and take a picture of your answers.With your webcam still on, take a picture of our exam answers and email me your answers from your phone (angela.hodgson@ndsu.edu)Type "Done" in the submission box below, and submit this exam.
