LS2. Ecosystems: Interactions, Energy, and Dynamics

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.
5-LS2-2(MA): Compare at least two designs for a composter to determine which is most likely to encourage decomposition of materials. Clarification Statement
  • Measures or evidence of decomposition should be on qualitative descriptions or comparisons.
