Question

If we weighed all of the organisms at each level of this food web, which would be the heaviest?

विकल्प

• Grass and trees

• Grasshoppers and squirrels

• Hawks and foxes

• All levels would weigh the same

Answer 1

Grass and trees

Explanation:

It is because producers like grass and trees form the base of the food web and have the greatest biomass. They support all other levels, and energy transfer between trophic levels is inefficient, so biomass decreases at each higher level. Hence, the total weight of organisms is highest at the producer level. The ecological pyramid of biomass explains this principle.
