Ecosystem Services and Ecology Concepts

The video lesson 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 cultural benefits like relaxation and historical insights, provisional resources like food and water, regulatory benefits through natural processes, and supporting services through resource cycles. The lesson concludes with a quiz to reinforce learning.
