Practice questions testing deep understanding of energy flow, ecological pyramids, and succession.
Q1. Assertion (A): The ecological pyramid of energy is always strictly upright and can never be inverted. Reason (R): According to the Second Law of Thermodynamics and the 10% law, energy is always lost as heat at each successive trophic level. Therefore, the energy available at the producer level must always be greater than the energy available at the herbivore level, making inversion physically impossible.
