If 10,000 J of energy is present at the T1 level, then what is the energy available at the T 2 level?

Options

  1. A1000 J
  2. B10 J
  3. C100 J
  4. D1 J

Correct answer

C. 100 J

Step-by-step solution

According to the 10 percent law, only 10% of the energy is transferred to each trophic level from its lower trophic level. If 10,000 joules of energy is available to the producer, then only 1000 joules 10000 × 10 / 100 = 1000 of energy will be available to the primary consumer and only 100 joules 1000 × 10 / 100 = 100 of energy will be available to T 2 organism.
