Question

Given diagram represents the pyramid of biomass. Select the correct order of organisms from the following.

• A. A ; Tree, B ; Bird, C ; Small insects, D ; Large insects
• B. A ; Dolphin, B ; Tuna, C ; Snail, D ; Phytoplankton
• C. A ; Snake, B ; Hawk, C ; Squirrel, D ; Nuts
• D. A ; Phytoplankton, B ; Zooplankton, C ; Small fish, D ; Large fish

Answer 1

The correct option is B A ; Dolphin, B ; Tuna, C ; Snail, D ; Phytoplankton

The pyramid of biomass is the graphical representation of the biomass present sequence-wise per unit area at different trophic levels of a food chain in an ecosystem. The given pyramid can be observed in a marine ecosystem, where the biomass of large fish is highest and phytoplankton has least biomass. As the biomass of consumers is larger than the biomass of producers, the biomass of marine organisms in increasing order will be: Phytoplankton → Snail → Tuna → Dolphin.
