The Essential Roles in the Food Chain and Ecosystem

The video tutorial introduces the concept of the food chain, explaining how organisms are interconnected through feeding relationships. It covers the roles of producers, consumers, and decomposers, detailing how energy flows from plants to various types of consumers and finally to decomposers. The tutorial also highlights the concept of a food web and concludes with trivia about humans' position in the food chain.
