उत्तर
Each prey population has a greater biomass than its predator population.
Explanation:
This is because in a food chain like grass → rabbits → snakes → hawks, biomass decreases at each successive trophic level due to energy loss. Therefore, prey populations have greater biomass than their predators to support the energy needs of the higher levels. This is a fundamental principle, represented by the biomass pyramid in ecology.
