Question

who many ecological pyramid are there​

Answer 1

Answer:

There are three ways we can represent the trophic levels in an ecological pyramid: the amount of organisms (number), the mass of all the organisms in each level (biomass), or the amount of energy contained in each level. Let's look at each of these pyramids in detail.

Answer 2

Answer:

Types of Ecological Pyramids

Depending on the factors that we use to represent an ecological pyramid, there are three types. They are:

1. Pyramid of numbers– Here the factor that is taken into account is the number of organisms in each trophic level. As we go up the levels of the pyramid, the number of organisms decreases. The producers form the largest number and hence are at the bottom of the pyramid.

2. Pyramid of energy– This is an upright pyramid that represents the flow of energy from the producers to the final consumers.

3. Pyramid of biomass – This pyramid represents the amount of biomass of the organisms present at each trophic level. Biomass is nothing but the weight of the organisms.
