What type of ecological pyramid would be obtained with the following data ?
Secondary consumer : 120 g
Primary consumer : 60 g
Primary producer : 10 g
Upright pyramid of numbers
Pyramid of energy
Inverted pyramid of biomass
Upright pyramid of biomass
As we learnt in
The pyramid of biomass -
Biomass refers to the total weight of living matter per unit area. In an ecosystem, the biomass decreases from the producer level to the consumer level.
-
• The given data depicts the inverted pyramid of biomass, usually found in aquatic ecosystem.
• Pyramid of energy is always upright
• Upright pyramid of biomass and numbers are not possible, as the data depicts primary producer is less than primary consumer and this is less than secondary consumers.
Option 1)
Upright pyramid of numbers
This is incorrect.
Option 2)
Pyramid of energy
This is incorrect.
Option 3)
Inverted pyramid of biomass
This is correct.
Option 4)
Upright pyramid of biomass
This is incorrect.
