Pyramid of biomass

Ecological pyramid-

An ecological pyramid is a graphical representation of the food chain.

in other words "Graphical representation of the tropical level of an ecosystem where producers occupied the base and top consumer occupy the top level pyramid.

There are three types of the ecological pyramid

1. pyramid of number-

The pyramid of the number shows the number of an organism to each trophic level of the ecosystem. it shows the relationship between producer herbivore, carnivores at a successive tropic level in terms of their number.

2. pyramid of energy

The pyramid of energy or the energy pyramid describes the overall nature of the ecosystem.it ensures that the energy flows from lower trophic level to higher trophic level.
The energy pyramid always upright and vertical. 
At each trophic level, there is successive loss of energy in the form of heat and respiration.

3. pyramid of biomass-

The pyramid of numbers depicts the relationship in terms of the number of producers, herbivores and the carnivores at their successive trophic levels.
