Interactions in Estuarine and Intertidal Ecosystems

The video explores the interactions within estuaries and intertidal zones, focusing on biotic and abiotic components. It covers various interactions like competition, predation, mutualism, and parasitism, providing examples for each. The role of the sun as an energy source and the classification of organisms into producers and consumers are discussed. The video also explains food chains and webs, highlighting the importance of detritus in nutrient cycling. A review section with questions helps reinforce the learning objectives.
