In a typical energy pyramid, approximately 10% of the energy from one trophic level is transferred to the next level, while the rest is lost due to metabolic processes and heat.
Given that the caterpillars contain 430 k cal of energy:
-
To find the energy available to the starling (next level up):
- 10% of 430 k cal = 0.10 × 430 = 43 k cal
-
To find the energy available to the owl (next level up from the starling):
- 10% of 43 k cal = 0.10 × 43 = 4.3 k cal
So, the responses to fill in the blanks would be:
- The amount of energy available to the starling would be 43 k cal.
- The amount of energy available to the owl would be 4.3 k cal.
