Exploring Food Chains and Food Webs

Mrs. Stone introduces the concepts of food chains and food webs, explaining how energy flows from the sun to producers and then to consumers. She discusses the roles of producers, consumers, predators, prey, scavengers, and decomposers in ecosystems. The video covers different types of consumers, such as herbivores, carnivores, and omnivores, and explains how food chains and webs illustrate these relationships. The importance of decomposers in recycling nutrients is also highlighted.
