Feeding Relationships and Predator-Prey Cycles in Ecosystems

The video discusses the interdependence of organisms in ecosystems, focusing on feeding relationships. It explores the impact of changes, such as the removal of grass, on community populations. Key ecological terms like producers, consumers, and food chains are defined. The predator-prey cycle is explained, highlighting how changes in prey populations affect predators and vice versa. The video concludes with a summary and preparation for assessment.
