Exploring Ecological Relationships: Competition, Predation, and Symbiosis

The video explores three types of relationships in ecosystems: competition, predator-prey, and symbiosis. It explains intraspecific and interspecific competition, where organisms compete for limited resources. Predator-prey dynamics are illustrated with examples like bears and salmon. Symbiosis is discussed with mutualism, commensalism, and parasitism, providing examples such as bacteria in humans and lampreys on fish. The video concludes with a call to subscribe for more educational content.
