Ecosystem Roles and Energy Flow

The video tutorial explores the roles of producers, consumers, and decomposers in nature. It explains how producers like plants use photosynthesis to create energy, while consumers such as herbivores, carnivores, and omnivores obtain energy by eating plants or other animals. Decomposers like mushrooms and bacteria break down dead matter into nutrients. The video encourages students to identify organisms and classify them as producers, consumers, or decomposers, enhancing their understanding of ecological roles.
