Question

What type of ecological pyramid would obtained with the following data ?
Secondary consumer : 120 g
Primary consumer      : 60 g
Primary producer       : 10 g
(1) Inverted pyramid of biomass
(2) Pyramid of energy
(3) Upright pyramid of numbers
(4) Upright pyramid of biomass

Answer 1

The correct option is(1) Inverted pyramid of biomass

Explanation:

An inverted pyramid of biomass will be obtained from the given data. The biomass is continuously decreasing from the secondary consumer (120 g) to primary consumer (60 g) to primary producer (10 g). Therefore, upright pyramid of biomass cannot be obtained. The data is given in the form of biomass, therefore the pyramid of number and energy cannot be obtained. Further, pyramid of energy is always upright.
