This modeling sequence allows students to explore how factors, both environmental and otherwise, can affect the relationships within an ecosystem through changes in population size.

Performance Expectations

5-LS2-1   Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.

MS-LS2-1   Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.

MS-LS2-3   Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.

MS-LS2-4   Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
