The performance expectations in LS2: Interactions, Energy, and Dynamics Relationships
in Ecosystems help students formulate an answer to the question, “How does a system of
living and non-living things operate to meet the needs of the organisms in an ecosystem?”
Students can analyze and interpret data, develop models, and construct arguments and demonstrate a deeper understanding of resources and the cycling of matter and the flow of energy in ecosystems. They can also study patterns of the interactions among organisms within an ecosystem. They consider biotic and abiotic factors in an ecosystem and the effects these factors have on population. They evaluate competing design solutions for maintaining biodiversity and ecosystem services.
MS-LS2-3. Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
