factors that affect biodiversity and the relationships between species and the physical environment in an ecosystem Reasoning and synthesis Students use at least two examples to make and defend a claim: The examples support the idea that: ● Modest biological or physical disturbances in an ecosystem result in maintenance of relatively consistent numbers and types of organisms. ● Extreme fuctuations in conditions or the size of any population can challenge the functioning of ecosystems in terms of resources and habitat availability, and can even result in a new ecosystem. *When “describe” is referenced, any of the following descriptions could be used: written, oral, pictorial, and kinesthetic. ● Students design a solution that involves reducing the negative effects of human activities on the environment and biodiversity, and that relies on scientifc knowledge of the factors affecting changes and stability in biodiversity. ● Examples of factors include but are not limited to overpopulation, overexploitation, habitat destruction, pollution, introduction of invasive species, and changes in climate. ● Students describe* the ways the proposed solution decreases the negative effects of human activity on the environment and biodiversity. Describing Criteria and Constraints ● Students describe* and quantify (when appropriate) the criteria (amount of reduction of impacts and human activities to be mitigated) and constraints (for example, cost, human needs, and environmental impacts) for the solution to the problem, along with the tradeoffs in the solution . Evaluating Potential Solutions ● Students evaluate the proposed solution for its impact on overall environmental stability and changes. ● Students evaluate the cost, safety, and reliability, as well as social, cultural, and environmental impacts, of the proposed solution for a select human activity that is harmful to an ecosystem. Refning and/or Optimizing the Design Solution ● Students refne the proposed solution by prioritizing the criteria and making tradeoffs as necessary to further reduce environmental impact and loss of biodiversity while addressing human needs. *When “describe” is referenced, any of the following descriptions could be used: written, oral, pictorial, and kinesthetic.
