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.

Answer 1

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

• Correct Response: There has been an increase in the Red-Tailed Hawk population.

An increase in the Red-Tailed Hawk population would likely lead to higher predation rates on Wood Rats, thereby decreasing their population.

Question 2:
Arrange the organisms in order from Trophic Level 1 (bottom) to Trophic Level 4 (top).

• Assuming the organisms in your food chain are typical (e.g., plants, primary consumers, secondary consumers, and apex predators), here’s a generic order:

1. Trophic Level 1: Primary Producers (e.g., plants or phytoplankton)
2. Trophic Level 2: Primary Consumers (e.g., herbivores like insects or small mammals)
3. Trophic Level 3: Secondary Consumers (e.g., small predators like snakes or birds of prey)
4. Trophic Level 4: Tertiary Consumers or Apex Predators (e.g., larger carnivores like hawks or mountain lions)

Please specify the actual organisms in your food chain if you want a precise arrangement.
