Food Chain

The video tutorial explains the concept of a food chain, which illustrates how living things obtain energy. It covers the roles of producers, consumers, and decomposers, and describes the process of photosynthesis. The video also categorizes consumers into herbivores, carnivores, and omnivores. Examples of food chains in different habitats, such as grasslands and oceans, are provided. The tutorial concludes by encouraging viewers to consider the impact of removing a link from the food chain.
