Flow of energy through an ecosystem
Learning objectives
- Understand the different ways to quantify the trophic relationships of a food chain.
An ecological pyramid is a quantitative representation of the trophic levels of a food chain. There are three types of ecological pyramids:
- Pyramid of numbers
- Pyramid of biomass
- Pyramid of energy
The detrivores and decomposers are not always represented in these pyramids but they play an essential role in the cycle of materials.
