Levels of Organization in the Ecosystem Explained

The video tutorial explains the concept of ecology, which is the study of relationships between living things and their environment. It discusses how living and nonliving components interact within ecosystems. The tutorial outlines the levels of biological organization from species to biome and explains the roles of biotic and abiotic factors in shaping ecosystems. Examples include the temperate forest biome and the impact of factors like hurricanes on ecosystems.
