In typical predator food chain involving secondary and tertiary consumers, the organism become progressively
In a typical predator food chain involving secondary and tertiary consumers, the organisms become progressively larger and fewer along the food chain. This is because the energy from the primary producers (plants) is transferred to the primary consumers (herbivores) and then to the secondary consumers (carnivores) and finally to the tertiary consumers (top carnivores). As this energy is transferred, a lot of it is lost as heat or used for metabolism, so there is less and less energy available for the higher levels of the food chain. Therefore, the organisms at the top of the food chain (tertiary consumers) tend to be larger in size and fewer in number compared to those at the bottom (primary producers and herbivores).
