6.4.1 What and Who Is In the Water?
Student Performance Expectation
6.4.1 Analyze data to provide evidence for the effects of resource availability on organisms and population in an ecosystem. Ask questions to predict how changes in resource availability affect organisms in those ecosystems. Examples could include water, food, and living space in Utah environments.
How and why do living and nonliving water quality factors in a waterbody change in relation to one another?
Disciplinary Core Ideas:
LS2.A: Interdependent Relationships in Ecosystems
- Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors.
- In any ecosystem, organisms and populations with similar requirements for food, water, oxygen or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction.
- Growth of organisms and population increases are limited by access to resources.
Cross Cutting Concepts:
- Cause and Effect
- Stability and Change in Systems
Science and Engineering Practices:
- Asking Questions and Defining Problems
- Planning and Carrying out Investigations
- Analyzing and Interpreting Data
