The document outlines a lesson plan for students to learn about ecosystems and interdependence between living and nonliving components. Students will explore a park to observe different plant and animal species. They will record information on each species' habitat and dependencies. Afterwards, students will plot all species on a world map in their natural habitats and illustrate which ones depend on each other for survival using color coordination. The goal is for students to understand how organisms rely on one another and their environment.
