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
Every Grade 8 Science Test question on MS-LS2-4 is written to match one of the performance level descriptions (PLDs) below.
Level 1: Identify an argument that describes how a change in a physical or biological component of an ecosystem will have an effect on a population. Spring 2026 Question 28
Level 2: Identify the empirical evidence that supports the argument that changes to physical or biological components of an ecosystem affect populations. Spring 2024 Question 47
Level 3: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations. Spring 2025 Question 50
Level 4: Construct an argument, supported by empirical evidence, that supports the claim that human activities cause changes to physical and biological components of an ecosystem, which affect populations.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of MS-LS2-4.
This section could be expanded upon. You can help out by adding to this section.
NGSS Dimensions
Performance expectation MS-LS2-4 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
Science and Engineering Practices
- Engaging in Argument from Evidence
- Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
Disciplinary Core Ideas
- 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.
Crosscutting Concepts
- Stability and Change
- Small changes in one part of a system might cause large changes in another part.
