Question

part b
if the shrimp at the bottom of this food chain has a total of 10,000 units of energy, how much of that energy will the bird receive?
a 1 unit
b 10 units
c 1000 units

Explanation:

Step1: Assume energy transfer rate

The 10% rule applies: ~10% energy passes to next trophic level.

Step2: Define food chain steps

Shrimp (level 1) → [missing organism] (level 2) → Bird (level 3). So 2 transfers.

Step3: Calculate energy for bird

First transfer: $10,000 \times 0.1 = 1,000$ units. Second transfer: $1,000 \times 0.1 = 10$ units.

Answer:

B. 10 units
