Question

Given below is one of the types of ecological pyramids. This type represents

(A) Pyramid of numbers in a grassland
(B) Pyramid of biomass in a fallow lake
(C) Pyramid of biomass in a lake
(D) Energy pyramid in a spring

Answer 1

HINT:
Before we proceed into the problem, it is important to know the definition of ecological pyramids.
An aquatic ecological pyramid is a diagram that helps to illustrate the relationship between different levels of an ecosystem. It can be used as a tool for monitoring and managing ecosystems, and it may also be helpful in understanding how human activity affects the environment.

COMPLETE STEP-BY-STEP SOLUTION:

Given that the biomass of producers and secondary consumers is lower than that of primary consumers, the given pyramid illustrates the biomass pyramid in an aquatic ecosystem. The pyramid takes on an inverted shape as a result. So the pyramid in the diagram is a biomass pyramid in a lake.
The biomass pyramid in a lake habitat is symbolized by the inverted pyramid. The inverted pyramid gets smaller at the bottom. As a result, this indicates that biomass increases gradually as trophic levels rise from the lowest to the highest.
The inverted pyramid gets smaller at the bottom. As a result, this indicates that biomass increases gradually as trophic levels rise from the lowest to the highest.
Therefore, this type of pyramid represents the Pyramid of biomass in a lake.
Hence, the option C is correct
NOTE:
Tiny phytoplankton are the producers in the aquatic ecosystem. This phytoplankton multiply and expand quickly. As a result, the base of the biomass pyramid is small, with consumer biomass outpacing producer biomass. The pyramid therefore uses inverted biomass.
