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 hawkk

To organize these organisms by trophic level, we start with Trophic Level 1 at the bottom, which consists of primary producers that generate energy through photosynthesis. As we move up the levels, energy decreases due to inefficiencies in energy transfer.

Here’s the order based on their trophic levels:

  1. A. Brittlebush - Trophic Level 1 (primary producer)
  2. B. Pallid-winged grasshopper - Trophic Level 2 (primary consumer, herbivore)
  3. C. Grasshopper mouse - Trophic Level 3 (secondary consumer, carnivore)
  4. D. Red-tailed hawk - Trophic Level 4 (tertiary consumer, top predator)

So, the complete 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
