Question 2
A student has pulled a Food Chain from the Food Web above. She wants to put the organisms into an Energy Pyramid to show the amount of energy in each level and how energy transfers from one level to the next.

Put the below organisms in order with Trophic Level 1 at the bottom and Trophic Level 4 at the top. This means the level containing the most energy is at the bottom and energy moves up towards the top level.

Question 1: Which change would lead to a decrease in the Wood Rat population?

The correct response is: There has been an increase in the Red-Tailed Hawk population.

This is because Red-Tailed Hawks are predators, and an increase in their population would likely lead to a decrease in the Wood Rat population as they would hunt and consume them.

Question 2: Put the below organisms in order with Trophic Level 1 at the bottom and Trophic Level 4 at the top.

To correctly arrange the organisms in an Energy Pyramid, we would typically have:

  • Trophic Level 1: Producers (e.g., plants or plant-like organisms)
  • Trophic Level 2: Primary Consumers (herbivores that eat the producers)
  • Trophic Level 3: Secondary Consumers (carnivores that eat the primary consumers)
  • Trophic Level 4: Tertiary Consumers (top predators that eat the secondary consumers)

Since I don't have the specifics of the organisms you mentioned to classify them, here’s a general example:

  1. Trophic Level 1: Plants (e.g., grass)
  2. Trophic Level 2: Herbivores (e.g., Pallid-Winged Grasshopper)
  3. Trophic Level 3: Primary carnivores (e.g., Collared Lizard)
  4. Trophic Level 4: Top predators (e.g., Red-Tailed Hawk)

Please adjust the organisms in the list based on what you had in mind for each trophic level.
