(Think about their relationships and use this to answer the question. Use appropriate terms when explaining.) 2. Draw the food chain these organisms would form. 6

10 Energy Flow Through Ecosystems Purpose: The transformations of energy in an ecosystem begin first with the input of energy form the sun. Energy from the sun is captured by the process of photosynthesis. The transfer of energy from the sun to producer to primary consumer to secondary consumer to tertiary consumer can be shown in a FOOD CHAIN. Procedure: 1. You will need to pour the water from your cup into the cup of the person behind you. If you are the FIRST person in line, you will need to count the number of cups you remove from the container. If you are the LAST person in line, you will need to measure the amount of water in the last container/pan. 2. Timekeeper: Start the energy transfer. Allow the transfer to continue for 3 minutes. Stop the transfer. 3. Line Judge: Monitor the passing of the water. No fingers over the holes. The water must be poured. Cups cannot be traded. 4. Recorder: Collect the number of cups the first person in each line removed and record in the data table. Record the amount of water in the final container/pan from each line. We will conduct 3 trials to collect out data. Use the chart on the following page to record data from all chain groups at the end of the activity. Use this information to answer the conclusion. Useful calculations: Conversion from cup to ml: Volume taken from container (ml) = Volume of cup in ml x Number times cup was filled Calculation of efficient of energy transfer: Efficiency = Volume of water in end container (ml) / Volume taken from container (ml) x

11 Data Table: Food Chain Trial 1 Vol taken from 1st container Trail 1 Vol. in final container Efficiency of energy transfer Trial 2 Vol taken from 1st container Trail 2 Vol. in final container Efficiency of energy transfer Trial 3 Vol taken fro 1st container Trail 3 Vol. in final container Efficiency of energy transfer Average Efficiency of energy transfer Graph it Create a line graph below using the average efficiency for each chain. 11

12 Conclusion: 1. Food Chain Length Analogies Decide what each of the items in the activity represent: Initial container: Cups with one hole, two holes, and three holes: Water: Water dripping from cups: 2. Below draw the activity we just did as a food web. Use the terms autotroph, heterotroph, producer, consumer, herbivore, carnivore, omnivore, scavenger as you label your food web below. 3. Consider all the energy that was lost to the food chain during this activity. In an actual ecosystem how would this energy be used? Explain. 12
