MS-LS2-5 Ecosystems: Interactions, Energy and Dynamics.Construct an argument, supported by evidence gathered through observation and experience, showing how changes to physical or biological components of an ecosystem affect populations. MS-LS2-4 Ecosystems: Interactions, Energy and Dynamics.Develop a model to describe the cycling of matter and flow of energy among living parts of the food chain. MS-LS2-3 Ecosystems: Interactions, Energy and Dynamics.Construct an explanation about how the different parts of the food chain are dependent on each other. MS-LS2-2 Ecosystems: Interactions, Energy and Dynamics.
Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem. MS-LS2-1 Ecosystems: Interactions, Energy and Dynamics.
If students understand the relationships in a simple food chain, they will better understand the importance and sensitivity of these connections, and why changes to one part of the food chain almost always impact another. By reviewing the relationships of organisms that feed on one another, this lesson explores how all organisms- including humans-are linked. All living organisms depend on one another for food.
