Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
Clarification statement: Emphasis is on describing the conservation of matter and flow of energy associated with ecosystem, and on defining the boundaries of the ecosystem.
Assessment boundary: Assessment does not include the use of chemical reactions to describe the processes.
Performance Level Descriptions
PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of four levels.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of MS-LS2-3.

Assessment
What assessment of MS-LS2-3 might look like on a NY state exam.

NGSS Dimensions
Performance expectation MS-LS2-3 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Developing and Using Models
- Develop a model to describe phenomena.
- LS2.B: Cycle of Matter and Energy Transfer in Ecosystems
- Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.
- Energy and Matter
- The transfer of energy can be tracked as energy flows through a designed or natural system.
