The topmost trophic level in a food chain is occupied by ____________.
The topmost trophic level in a food chain is occupied by tertiary consumers. In a food chain, the energy flows from the first tropic level - producers to the topmost tropic level- tertiary consumers. The energy flow is unidirectional and follows the 10% Law, which means that the higher trophic levels have less energy, i.e., limiting the number of top predators.
The trophic levels in the food chain are as follows:
1. Producers (Autotrophs)
2. Primary Consumers (Herbivores)
3. Secondary Consumers (Carnivores/Omnivores)
4. Tertiary Consumers (Apex Predators)
