Modelling energy with pyramid diagrams (2025)
To investigate energy in ecosystems uses the concepts of "trophic levels". This activityexplains how to build a pyramid of energy and then how to use it to illustrate the differences in energy conversion ratios between species in a food web such as grasshoppers and mammals like cows and rabbits. Students are expected to make comparisons and explain the pyramids of energy from different ecosystems through some IB...
