Question

Explain the pyramid of biomass with one example.

Answer 1

Shows the total dry weight (standing crop) of organisms at each trophic level at a given time.

• Upright example (grassland): Grass biomass > herbivore biomass > carnivore biomass
• Inverted example (aquatic ecosystem): Phytoplankton biomass is less than zooplankton biomass because phytoplankton has a short life span and is rapidly grazed.
