Question

In a pyramid of biomass, if the total dry weight (kgm^-2) of primary produces is about 809, it well increases at tertiary consumer level up to ______.

Options

• 37 kgm^-2 

• 11 kgm^-2 

• 5 kgm^-2 

• 1.5 kgm^-2

Answer 1

In a pyramid of biomass, if the total dry weight (kgm^-2) of primary produces is about 809, it well increases at tertiary consumer level up to 1.5 kgm^-2.

Explanation:

The biomass at each trophic level is represented by a pyramid of biomass in an ecological pyramid. There is a rapid drop in biomass at higher trophic levels in a biomass pyramid. Primary producers have dry biomass of 809 kg/m² in a biomass pyramid. At the primary consumer level, biomass will be 37 kg/m². At the secondary consumer level, biomass will be 11 kg/m². At the tertiary consumer level, biomass will be 1.5 kg/m².
