Question

The pyramid of biomass in a sea is
A) Upright
B) Slanting
C) Horizontal
D) Inverted

Answer 1

Hint: A diagrammatic representation of the amount of living organic matter in each trophic level.

Complete step-by-step answer:
Biomass is the amount of living organic matter. The graphical representation of the pyramid of biomass is the biomass sequence wise person unit area of different trophic levels.
The pyramid of biomass in the sea is inverted because the amount of biomass is least at the base of the pyramid and the amount of biomass is maximum at the apex of the pyramid.
The first trophic levels consist of producers which are phytoplanktons that have the least biomass while the last trophic levels consist of carnivores which are fishes that have maximum biomass.

Additional information:
1. The pyramid of biomass represents the relationship that exists between the quantity of living matter at different trophic levels.
2. The biomass of a trophic level is dependent upon the longevity and reproductive potential of members.
3. The number of generations of phytoplanktons may be consumed by a single generation of zooplanktons.
4. Biomass of fish is large as fishes are larger with a longer lifespan and several generations of zooplanktons can be consumed by fishes.
5. The marine environment has an inverted biomass pyramid.
So, the correct answer is Inverted.

Note: An ecological pyramid is a graphical representation of the relationship between different organisms in an ecosystem. Ecological pyramids are of three types: the pyramid of a number, the pyramid of biomass, and the pyramid of energy.
