Ecology Review

This activity engages students in understanding food chains by arranging various organisms into the correct trophic levels and illustrating their feeding relationships. Participants will label the arrows representing energy flow and inputs/outputs in these chains, exploring concepts like energy movement, carbon cycling, and the interconnectedness of ecosystems. Through this exercise, students will grasp how energy is transferred from producers to consumers and the significance of each trophic level in maintaining ecological balance.

  1. Ecology Review

  2. Put these organisms into a food chain and link them with arrows in the right direction Food chains

  3. Now join the animals to show feeding relationships Put the pictures in the right trophic levels

  4. Energy Heat • Label the arrows that represent the energy inputs and energy outputs Food Movement 10% left to go to the next trophic level Waste

  5. So if I were to draw a pyramid of energy to show how much energy there was at each trophic level would it look like this: Tertiaryconsumer Tertiary consumer Or…. Secondary consumer Secondary consumer Primary consumer Primary consumer Producer Producer Or…. Tertiary consumer Secondary consumer Primary consumer Producer

  6. Where does all this energy that is passing around come from originally?

  7. Label the arrows Carbon Cycle CO2 in Air 1.Photosynthesis 2.Respiration 3.Eating 4.Death 5.Fossilisation 6.Combustion 7.Decay and decomposition 1 2 6 7 4 2 Carbon in dead organic matter 3 5 5 4
