Question

The upright pyramid of number cannot be seen with ecosystem.

• A. Lake
• B. Grassland
• C. Pond
• D. Forest

Answer 1

Answer:

D. Forest

• Pyramid of numbers represents the number of individuals per unit area at various trophic levels.

• It is always upright in grassland, pond and lake ecosystems.

• But in a forest, it is a partly upright pyramid of numbers because the number of producers are lesser in number and support a greater number of herbivores and which in turn support a fewer number of carnivores.
