Environmental Matter Cycling
Next Generation Standards
5-LS2-1 - Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
Clarification Statement - Emphasis is on the idea that matter that is not food (air, water, decomposed materials in soil) is changed by plants into matter that is food. Examples of systems could include organisms, ecosystems, and the Earth.
Assessment Boundary - Assessment does not include molecular explanations.
5-LS2-1 - Develop a model to describe the movement of matter among producers, consumers, decomposers, and the air, water, and soil in the environment to (a) show that plants produce sugars and plant materials, (b) show that animals can eat plants and/or other animals for food, and (c) show that some organisms, including fungi and bacteria, break down dead organisms and recycle some materials back to the air and soil.
Clarification Statement - Emphasis is on matter moving throughout the ecosystem.
Assessment Boundary - Molecular explanations, or distinctions among primary, secondary, and tertiary consumers, are not expected in state assessment.
