WHAT IS ECOLOGICAL PYRAMID?

ECOLOGICAL PYRAMID

• Ecological pyramid is the diagrammatic representation of data of each trophic level in an ecosystem.
• Ecological pyramid has three types which are given below:

1.  Pyramid of number
2.  Pyramid of biomass
3.  Pyramid of energy flow

1. Pyramid of number :

If we place one by one producer, Primary consumer, Secondary consumer and territory on the basis f their number in pyramid. So it is called pyramid of numbers.

2.Pyramid of biomass :

If we place one by one organisms on the basis of their biomass in the pyramid for a particular area is called pyramid of biomass.

3. Pyramid of energy flow :

If we consider energy utilize by every trophic level in an ecosystem in a unit area and arrange them in a pyramid from basis of energy utilization is called pyramid of energy flow.
