Components of a Stable Ecosystem 5E Instructional Model Plan
Resource:
Components of a Stable Ecosystem 5E Instructional Model Plan
Stable ecosystems are complex and dynamic systems that rely on the interconnectedness between organisms and between organisms and their environment. In this sequence, students explore the components and organization of ecosystems, how energy flows through food chains and webs, and how nutrients are cycled to maintain life.

Population Dynamics 5E Instructional Model Plan
In stable ecosystems, populations are often in a state of dynamic equilibrium; following cycles of increasing and decreasing based on feeding relationships and resource availability. In this sequence, students explore how predator-prey and symbiotic relationships highlight the interdependence of living things and between living things and their environment.
