Solution

The correct option is A 1 only
Pyramid of Biomass depicts the amount of dry mass of organic matter in grams per square metres. In grassland and forest, it is upright. However, in a pond as the producers are small organisms, their biomass is least, and this value gradually shows an increase towards the apex of the pyramid, thus making the pyramid inverted in shape.
