Which of the following statements regarding forest ecosystems is/are incorrect?

1. The number pyramid is neither inverted nor upward.
2. The biomass pyramid is inverted.

In a forest ecosystem, the producers are large size trees which make the base of pyramid. The herbivores such as fruit eating birds, deer, elephants, etc. make the primary consumers and are less than primary producers. After that, the number goes down at each successive level. Thus, a pyramid of numbers in a forest ecosystem is partially upright or spindle shaped. Biomass pyramid is upright in a forest ecosystem because a larger net biomass of producers supports a smaller weight of consumers.
