Description
Utah SEEd Strand 6.4 Assessments: This resource is a set of assessments for the Stability and Change in Ecosystems. There are assessments for each standard in the Utah SEEd 6.4 strand. These include multiple-choice and short-answer questions. These can be used as a quiz at the end of each standard being taught, or as practice and assessment at the end of the year.
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.
Utah SEEd 6.4.1
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 affect organisms in those ecosystems. Examples could include water, food, and living space in Utah environments.
Utah SEEd 6.4.2
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.
Standard 6.4.3
Develop a model to describe the cycling of matter and the 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)
Standard 6.4.4 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)
Utah SEEd 6.4.5 Evaluate competing design solutions for preserving ecosystem services that protect resources and biodiversity-based on how well the solutions maintain stability within the ecosystem. Emphasize obtaining, evaluating, and communicating information of different 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, water quality, and prevention of soil erosion.
