The path of energy in food from one organism to another is a?

The path of energy in food from one organism to another is known as a food chain or food web. It illustrates how energy is transferred through various trophic levels, starting from producers (like plants) that capture energy from the sun, to primary consumers (herbivores), and then to secondary and tertiary consumers (carnivores). Each step in this transfer involves energy loss, primarily as heat, following the laws of thermodynamics. Ultimately, this interconnected system highlights the flow of energy and nutrients in an ecosystem.
