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.

A. Brittlebush
B. Pallid-winged grasshopper
C. Grasshopper mouse
D. Red-tailed hawk

To order the organisms by their trophic levels, we start from Trophic Level 1 (producers) at the bottom and move up to Trophic Level 4 (top predators) at the top:

  1. A. Brittlebush - This is a producer (plant), which converts sunlight into energy through photosynthesis. (Trophic Level 1)
  2. B. Pallid-winged grasshopper - This is a primary consumer that feeds on plants (herbivore). (Trophic Level 2)
  3. C. Grasshopper mouse - This is a secondary consumer that preys on primary consumers like grasshoppers. (Trophic Level 3)
  4. D. Red-tailed hawk - This is a tertiary consumer and top predator that preys on small mammals, including grasshopper mice. (Trophic Level 4)

So the order from Trophic Level 1 to Trophic Level 4 is:

  1. A. Brittlebush
  2. B. Pallid-winged grasshopper
  3. C. Grasshopper mouse
  4. D. Red-tailed hawk
