Roles in Ecosystems

The video explores the ecosystem roles of plants, bacteria, and animals. It begins by identifying plants as living things in a meadow and explains how they produce energy through photosynthesis. The concept of producers, including plants and certain bacteria, is introduced, followed by consumers like animals that eat plants. Finally, the role of decomposers, such as bacteria that break down dead matter and recycle nutrients, is discussed.
