Pyramid of Biomass

Pyramid of Energy.

Answer 2

$\huge\boxed{\fcolorbox{red}{grey}{Answer}}$

▪ The relation between producers and consumers in an ecosystem can be graphically represented in the form of a pyramid called ecological pyramid.

▪ Structure: The base always represents the producers or the first trophic level and the apex represents top level consumer or the last trophic level.

▪ Ecological pyramids are of three types:

i. Pyramid of number

ii. Pyramid of biomass

iii. Pyramid of energy

i. Pyramid of number: The relationship between producers and consumers in an ecosystem can be represented in the form of a pyramid in terms of number called pyramid of number.

ii. Pyramid of biomass: The relationship between producers and consumers in an ecosystem can be represented in the form of a pyramid in terms of biomass called pyramid of biomass. It can be

a. Upright, e.g., in case of grassland ecosystem; or

b. Inverted, e.g., in case of pond ecosystem.

iii. The relationship between producers and consumers in an ecosystem can be represented in the form of a pyramid, in terms of flow of energy called pyramid of energy. It is always upright because energy is always lost as heat at each step.
