What are Food Chains and Food Webs?

A food chain is a straightforward sequence demonstrating the transfer of energy and nutrients from one living organism to another. It begins with a primary energy source, usually the sun, and flows through various trophic levels, including producers (plants), consumers (herbivores, carnivores, omnivores), and decomposers. Each step in a food chain represents a different trophic level, and energy is transferred from one level to the next. A food web consists of a complex network of linked food chains within an ecosystem. Unlike a linear food chain, a food web shows multiple pathways through which energy and nutrients flow among various organisms. It demonstrates how different food chains are linked and how species interact with each other. Enroll now at Tutoroot.
