GCSE Biology - Interdependence - Community and Competition #84

The video tutorial explains the relationships organisms have with each other and their environment, highlighting how changes in one part of an ecosystem can affect the whole. It introduces key ecological terms such as habitat, population, community, biotic and abiotic factors, and ecosystem. The video also covers the concept of competition for resources among organisms and the idea of interdependence, illustrated through food webs. Understanding these relationships helps predict the effects of changes within ecosystems.
