Ecological Pyramids - Ecosystem

The ancient Egyptians constructed elaborate tombs called pyramids. The base of the pyramid is broad and it supports the upper levels of the structure and it narrows to a point at the top. A similar situation is seen when we study and depict the trophic relationships in an ecosystem. The different trophic levels of an ecosystem are related to one another and can be summarised in the form of ecological pyramids. The base of each pyramid represents the producers or the first trophic level while the apex represents tertiary or high-level consumers; other consumer trophic levels are in between.
