IB Biology Topic C4.2.3 Flow of Chemical Energy Through Food Chains Revision Notes (SL/HL) | RevisionDojo

Written by official IB examiners

Chemical Energy Passes One Way Along a Food Chain and Cannot Be Recycled

Producers such as plants, algae, and some bacteria capture sunlight by photosynthesis and store it as chemical energy in carbon compounds.
Primary consumers such as zebras eat producers and take in this chemical energy.
Secondary consumers such as lions eat the herbivores and gain energy from their tissues.
Tertiary consumers such as apex predators feed on the secondary consumers, receiving what energy remains.

Note

Because energy is lost at each step, ecosystems have many more producers than herbivores and fewer predators than prey.
