Exploring Trophic Levels: Producers to Consumers

The video explains trophic levels in a food chain, starting with producers like plants that use photosynthesis. It describes primary consumers (herbivores), secondary consumers (carnivores), and tertiary consumers, highlighting energy transfer and loss at each level. Omnivores and decomposers are also discussed, emphasizing their roles in ecosystems.
