Detailed Solution

The above given statement is false.
Concept- A biomass pyramid expresses the total biomass of the species present at each trophic level of the environment using an ecological pyramid. Biomass can be shown as either dry weight or calories per unit area. A live organism's particular position in a food chain is known as its trophic level.
Producers, primary, secondary, and tertiary consumers make up a biomass pyramid. The producers are at the bottom of the food chain, followed by primary consumers at the top, and then secondary and tertiary consumers on top of the primary consumers.
The total number of different organisms present at each trophic level of an ecosystem is represented by the ecological pyramid of numbers. It shows the population at every level of the food chain.
The correct statement is a pyramid of biomass is based on the biomass (dry weight) present at each trophic level.
Hence, the correct option is 2.
