• A. Pyramid of energy in forest ecosystem
• B. Pyramid of biomass in forest ecosystem
• C. Pyramid of numbers in grassland ecosystem
• D. Pyramid of numbers in forest ecosystem

Answer 1

Answer: (D)

Pyramid of numbers in forest ecosystem

The given pyramid best represents pyramid of numbers in forest ecosystem as it is spindle-shaped. The producers are giant size trees in the forest ecosystem, and they form the base of the pyramid. The producers are usually less in number, but they support a higher number of herbivores such as deer, birds and elephants. The number goes down at each succeeding level as the primary consumers support very fewer numbers of carnivores. This results in a spindle-shaped structure of the pyramid of numbers in the forest ecosystem.
