| With reference to forest ecosystems, consider the following statements: |
| 1. The number pyramid is neither inverted nor upward. |
| 2. The biomass pyramid is inverted. Which of the statements given above is/are correct? |
A) 1 only
B) 2 only
C) Both 1 and 2
D) Neither 1 dot 2
Correct Answer: A
Solution :
[a] Forest ecosystem has a partly upright pyramid of number. This is 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. Biomass pyramid is upright in a forest ecosystem because a larger net biomass of producers support a smaller weight of consumers.
