7. Draw the picture showing how photosynthesis and cellular respiration cycle. Include the words in your diagram glucose, oxygen, carbon dioxide, cellular respiration, photosynthesis, inputs/reactants, outputs/products

8. Create your own energy pyramid. Include how energy enters and exits the system as well as what happens between each step.

Make it seem like a 9th grader wrote it!!!

7. Photosynthesis and Cellular Respiration Cycle Diagram

[Diagram Instruction: Since I can't draw, I'll describe how to create the diagram.]

  1. Start with Photosynthesis:

    • Draw a large green circle labeled "Photosynthesis".
    • Inside this circle, write "Inputs/Reactants: Carbon Dioxide + Water + Sunlight" on one side.
    • On the other side, write "Outputs/Products: Glucose + Oxygen".

  2. Connect to Cellular Respiration:

    • Draw an arrow from the "Outputs/Products" of photosynthesis to a new circle labeled "Cellular Respiration".
    • In the Cellular Respiration circle, write "Inputs/Reactants: Glucose + Oxygen".
    • On the other side of this circle, write "Outputs/Products: Carbon Dioxide + Water + Energy (ATP)".

  3. Cycle Back:

    • Draw an arrow from the "Outputs/Products" of cellular respiration back to the "Inputs/Reactants" of photosynthesis.

  4. Add Labels:

    • Make sure to indicate that photosynthesis occurs in plants and some algae, while cellular respiration occurs in animals and plants.

Overall, the diagram should clearly show that plants take in carbon dioxide and water to produce glucose and oxygen through photosynthesis, while organisms use glucose and oxygen to create energy, producing carbon dioxide and water through cellular respiration.

8. Energy Pyramid

Energy Pyramid Structure:

  • Top Level (Tertiary Consumers):

    • Animals like hawks or lions.
    • Energy enters: This level receives energy by consuming secondary consumers.
    • Energy exits: Only about 10% of the energy from the level below gets passed up.

  • Second Level (Secondary Consumers):

    • Animals like snakes or foxes.
    • Energy enters: They obtain energy by consuming primary consumers.
    • Energy exits: Again, they only pass about 10% of their energy to the level above.

  • Bottom Level (Primary Consumers):

    • Herbivores like rabbits or deer.
    • Energy enters: This level gets energy by consuming producers (plants).
    • Energy exits: They retain about 10% of the energy and pass 10% to the secondary consumers.

  • Base Level (Producers):

    • Plants and trees.
    • Energy enters: Plants get their energy directly from the sun through photosynthesis.
    • Energy exits: They convert sunlight into chemical energy (glucose), which is then eaten by primary consumers.

Summary of Energy Flow: Energy flows from the sun to the producers, then from producers to primary consumers, followed by secondary consumers, and finally to tertiary consumers. At each step, energy is lost (about 90%) to other processes (like metabolism and heat), meaning that only about 10% of the energy moves up to the next trophic level. This energy loss means that there are far fewer top-level predators than there are producers at the bottom of the pyramid!
