Ecological Interactions and Energy Flow

The video discusses ecological interdependence, interactions, and the study of ecology. It explains the classification of ecological interactions into populations, communities, ecosystems, and the biosphere. The video covers species interactions like competition, symbiosis, and feeding, and details energy flow through ecosystems, highlighting producers, consumers, and decomposers. It emphasizes the importance of balance in ecosystems and how organisms adapt to changes.
