The Intricate Web of Life Within Ecosystems

The video tutorial explains the concept of the food chain in ecosystems, starting with producers like plants that create energy through photosynthesis. It then describes consumers, including herbivores, carnivores, and omnivores, which rely on other organisms for energy. Decomposers, such as bacteria and fungi, break down dead matter, returning nutrients to the soil. The video concludes with trivia about humans' place in the food chain and introduces the concept of a food web.
