Building a power pyramid activity
Purpose: learners will gain an understanding showing how energy flows through an ecosystem by constructing an energy pyramid and establishing how much energy is moved between trophic levels
Components: *energy pyramid template, varieties list, pyramid data piece, calculator, one particular 1, 000ml beaker, a few clear glasses, one 1ml pipette, coop or pad
Question: just how much energy can be transferred in one trophic level to the next trophic level?
Method 1: ingredients label each standard of the energy pyramid with the suitable term: producer, primary client, secondary client, and tertiary consumer.
Process 2: labeled each degree of the energy pyramid with the appropriate term: trophic level1, trophic level a couple of, trophic level 3, and trophic level 4.
Process 3: through the species list, select organisms to represent every single level of the pyramid. Write the name in the organism inside the appropriate level.
Procedure four: observe the fresh data in table 1 )
Procedure 5: write the brands of the microorganisms that you chosen in part inside the appropriate put on the desk.
Procedure 6th: calculate the % of energy transferred in the 1st trophic level for the 2nd level. Divide strength from level1 and grow by 75. This quantity is the % of energy moved.
Procedure several: calculate the % of one's transferred by trophic level 2 to level a few and so forth.
Procedure 8: serve tap water in the 1, 000 ml beaker.
Add 1-2 drops of food coloring to the water and beat.
Procedure 9: line up the 3 cups. Check out your computations in table 1: how much energy was transferred from trophic level 1 to 2? Pour that % from the 1, 000ml in to the 1st glass.
Procedure 10: how much strength was transmitted from the second level for the 3rd level? _ _ _% put that % from cup 1 into cup 2 Procedure 14: repeat intended for the next trophic level/cup 3
