Food Chain Roles and Functions

This video tutorial introduces the concept of food chains within ecosystems, explaining how energy is transferred from one species to another. It covers the roles of producers, consumers, and decomposers, and discusses different types of consumers such as herbivores, carnivores, and omnivores. The tutorial includes practice exercises to classify organisms and concludes with a summary of key points.
