Question

(i) Draw a pyramid of numbers where a large number of insects are feeding on the leaves of a tree. What is the shape of this pyramid?
(ii) Will the pyramid of energy also be of the same shape in this situation? Give reason for your response.

Edvaya · Accepted Answer

The correct answer is Subjective. **SOLUTION** **(i) Pyramid of Numbers:** * **Base (Primary Producer - PP):** Tree (Number = 1) * **Top (Primary Consumer - PC):** Insects (Number = Many) Because a single tree supports a massive population of insects, the shape of this specific pyramid of numbers is **Inverted** (or spindle-shaped). **(ii) Pyramid of Energy:** **No**, the pyramid of energy will absolutely not be inverted. *Reason:* The pyramid of energy is governed by the laws of thermodynamics and is **always upright**. This is because a significant amount of energy is always lost as heat during respiration at every step, meaning the energy steadily decreases as it flows from the producer (Tree) to the primary consumer (Insects).
