MS-LS2-4 | Ecosystem Impacts on Population
Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
Clarification statement: Emphasis is on recognizing patterns in data and making warranted inferences about shifts in populations due to changes in the ecosystem.
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 five levels.

NGSS Dimensions
Performance expectation MS-LS2-4 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Engaging in Argument from Evidence
- Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
- LS2.C: Ecosystem Dynamics, Functioning, and Resilience
- Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.
- Stability and Change
- Small changes in one part of a system might cause large changes in another part.
