Ecosystem Services and Functions

The video tutorial introduces seventh graders to the concept of ecosystem services, covering cultural, provisional, regulatory, and supporting services. It begins with a review of invasive species and the definition of ecology. The lesson explains how ecosystems provide resources, regulate natural processes, and support life cycles. The teacher uses examples like oysters filtering water to illustrate these concepts. The session concludes with a quiz to reinforce learning.
