Levels of Organization in Ecology Explained

The video tutorial introduces ecology as the study of interactions between living things and their environment. It explains the levels of organization in ecology, starting from the individual organism, moving to populations, communities, ecosystems, biomes, and finally the biosphere. Each level is described in terms of its components and interactions, with examples such as coniferous forests and tropical rainforests. The tutorial emphasizes the interconnectedness of these levels and the impact of human activities on the biosphere.
