To calculate the energy available to tertiary consumers in a forest ecosystem, we can use the 10% energy transfer rule at each trophic level.

  1. Primary Producers: 50,000 kcal (this is the initial energy).
  2. Primary Consumers: 10% of 50,000 kcal = 5,000 kcal.
  3. Secondary Consumers: 10% of 5,000 kcal = 500 kcal.
  4. Tertiary Consumers: 10% of 500 kcal = 50 kcal.

Thus, the energy available to tertiary consumers would be 50 kcal.

The correct response is 50 kcal.
