What is the Food Chain?

The video tutorial explains the concept of food chains, which illustrate how living things obtain energy. It covers the roles of producers, consumers, and decomposers in ecosystems. Producers, like plants, create their own food through photosynthesis. Consumers, such as herbivores, carnivores, and omnivores, obtain energy by eating plants or other animals. Decomposers recycle nutrients from dead organisms. The video provides examples of food chains in grasslands and ocean habitats and encourages viewers to consider the effects of removing a link from the chain.
