What are ecological pyramids explain pyramid of numbers with examples?

Pyramid of number- The pyramid that gives the number of organisms at each trophic level is called pyramid of number. For example- oak → caterpillar → blue tit → sparrowhawk. The producer in the given food chain is the oak plant.

What are ecological pyramids explain pyramid of numbers and pyramid of energy?

The graphical representation of the relationship between various living beings at various trophic levels within a food chain is called an ecological pyramid. The pyramid is formed on the basis of the number of organisms, energy and biomass, and just like the name suggests, these are shaped in the form of a pyramid.

What are ecological pyramids describe with examples pyramid of number and biomass?

Pyramids of number represents the number of organisms at each trophic level. For example in the grassland ecosystem the number of plants is the highest followed by number of primary consumer that is mice. Followed by Snake and eagle .

What are ecological pyramids give examples?

An ecological pyramid is a graphical representation of the relationship between different organisms in an ecosystem. Each of the bars that make up the pyramid represents a different trophic level, and their order, which is based on who eats whom, represents the flow of energy.

What is an example of an energy pyramid?

An example of an energy pyramid is the forest ecosystem. In this ecosystem the producers are green plants that make up the bottom of the pyramid. Next, are the primary consumers, then secondary consumers, and finally the tertiary consumers make up the top triangle of the pyramid.
