Ecosystem Roles and Food Chains

This video tutorial covers the concept of harmony within ecosystems, focusing on food chains and webs. It explains the roles of different organisms, such as producers, consumers, and decomposers, and how they interact within an ecosystem. The tutorial includes a series of questions that help identify various consumer levels, apex predators, and the impact of population changes. It also discusses the role of herbivores in controlling plant populations and the effects of natural disasters on ecosystems. The video concludes with a summary of key points discussed.
