Ecology Concepts and Interactions

The video tutorial on ecology covers the organization of living organisms on Earth, defining ecology, and the factors affecting an organism's survival. It explains the levels of ecological organization, starting from the individual organism to the biosphere, and describes the roles of ecologists. The tutorial also discusses the interactions between organisms and their environments, including abiotic factors, and provides a detailed overview of biomes and the biosphere.
