Question

Which statement is true corresponding to the given food chain?
Grass $\to$ Rabbits $\to$ Snakes $\to$ Hawks

• A. Each predator population has a greater biomass than its prey population.
• B. Each prey population has a greater biomass than its predator population.
• C. Each population is omnivorous.
• D. Each level of food chain returns inorganic nutrients and energy to the producer.

Answer 1

The correct option is B Each prey population has a greater biomass than its predator population.

In most ecosystems, all the pyramids of number, energy and biomass are upright i.e., producers are more in number and biomass than the herbivores and herbivores are more in number and biomass than the carnivores. Also energy at a lower trophic level is always more than that at a higher level.
