What does a trophic level represent?

A trophic level represents a step in a food chain or web, indicating the position of an organism in relation to energy flow through an ecosystem. Each trophic level corresponds to a specific role in the transfer of energy, primarily defined by what an organism eats and what eats it. For instance, producers such as plants occupy the lowest trophic level, followed by primary consumers (herbivores), secondary consumers (carnivores), and so on. This hierarchical structure helps illustrate the relationships between different organisms, showing how energy is transferred and who relies on whom for nourishment within the ecosystem. This framework is essential for understanding ecological dynamics, biodiversity, and the interdependence of species.
