Levels of Organization in Ecosystems and Their Ecological Relationships

The video introduces ecology, focusing on the relationships between organisms and their environments. It explains the levels of organization in an ecosystem: organism, population, community, and ecosystem. The video also defines biomes and habitats, emphasizing the importance of both biotic and abiotic factors in these systems.
