Ecology Concepts and Definitions

The video tutorial on ecology covers the study of interactions between organisms and their environments. It introduces the concept of ecological organization, starting from individual organisms to populations, communities, ecosystems, biomes, and the biosphere. Each level is defined and explained, highlighting how organisms interact with each other and their non-living environments. The tutorial also touches on the distinct climates of biomes and the comprehensive nature of the biosphere.
