Strand 6.4: STABILITY AND CHANGE IN ECOSYSTEMS
The study of ecosystems includes the interaction of organisms with each other and with the physical environment. Consistent interactions occur within and between species in various ecosystems as organisms obtain resources, change the environment, and are affected by the environment. This influences the flow of energy through an ecosystem, resulting in system variations. Additionally, ecosystems benefit humans through processes and resources, such as the production of food, water and air purification, and recreation opportunities. Scientists and engineers investigate interactions among organisms and evaluate design solutions to preserve biodiversity and ecosystem resources.

6.4.1 Resources impact on Organisms
Students will be able to Analyze data to provide evidence for the effects of resource availability on organisms and populations in an ecosystem. Ask questions to predict how changes in resource availability affects organisms in those ecosystems. Examples could include water, food, and living space in Utah environments. (LS2.A)

Do the Uinta Forest Investigation
Track your learning as the assessment is going to have you come up with a claim about the forest with reasons and evidence you learned from the investigation. There is a google form assessment that you will fill out about your learning when you are done. Take good notes on the work you do so that you can give good evidence to back up your thinking on the assessment

The largest pelican breeding ground is on Gunnison Island in the Great Salt Lake. Is this the best place for them to have nests and raise their young?
As you go through these documents, look for evidence on what resources are being impacted and how it is causing change.

Make predictions about how the change in resources are going to impact the pelicans. You will have an assessment on this information.

6.4.2 Explain interactions of organisms
Students will be able to Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems. Emphasize consistent interactions in different environments such as competition, predation, and mutualism. (LS2.A)
6.4.3 Develop a model to explain the flow of energy
Students will be able to Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem. Emphasize food webs and the role of producers, consumers, and decomposers in various ecosystems. Examples could include Utah ecosystems such as mountains, Great Salt Lake, wetlands, and deserts. (LS2.B)
6.4.4 Describe the stability of a polpulation
Students will be able to Construct an argument supported by evidence that the stability of populations is affected by changes to an ecosystem. Emphasize how changes to living and nonliving components in an ecosystem affect populations in that ecosystem. Examples could include Utah ecosystems such as mountains, Great Salt Lake, wetlands, and deserts. (LS2.C)

6.4.5 Evaluate design solutions
Students will be able to Evaluate competing design solutions for preserving ecosystem resources and biodiversity based on how well the solutions maintain stability within the ecosystem. Emphasize obtaining, evaluating and communicating information of differing design solutions. Examples could include policies affecting ecosystems, responding to invasive species or solutions for the preservation of ecosystem resources specific to Utah, such as air and water quality and prevention of soil erosion.
