From producers to consumers, energy is exchanged between species in food chains.
In an ecosystem, a food chain is the series of events in which one living organism consumes another, which is subsequently consumed by a bigger organism.
The flow of nutrients and energy from one organism to the next at various trophic levels is referred to as a food chain.
The food chain also explains the eating pattern and interactions between living organisms.
The sequence in which producers, primary, secondary, and tertiary consumers occur in a food chain, starting at the bottom with producers and ending with primary, secondary, and tertiary consumers, is referred to as the trophic level. The lowest level of a food chain is the trophic level.
