Symbiosis describes a relationship between two organisms in an environment. There are three main types of relationships: mutualism, parasitism, and commensalism.
The classroom resource provides a video that will describe the different ways organisms can interact within an ecosystem. There is also a short test that can be used to assess students' understanding.
Students engage with a variety of resources to learn about ecosystems and the interactions among organisms in ecosystems, with a focus on elk migration in the Greater Yellowstone Ecosystem. Groups create a second map layer for their unit project that shows how their focal animal’s migration impacts its ecosystem. This lesson is part of the Detours and Distractions: How Humans Impact Migration Patterns unit.
