Question

The pyramid of energy in a forest ecosystem is

• A. Always upright
• B. Always inverted
• C. Both upright and inverted
• D. None of the above

Answer 1

Answer: (A)

Ecological pyramid is the graphic representation of an ecological parameter (number, biomass or energy).

The ecological pyramid can be upright, inverted or spindle shaped. The pyramid of energy gives graphic representation of flow of energy in different trophic levels. It is always upright because only 10 percent of energy is transferred from one trophic level to the next.

Thus, the correct answer is option A.
