c. Predict how an ecosystem will change as a result of major changes in an abiotic and/or biotic factor.
e. Analyze interactions within an ecosystem (e.g., water temperature and fish species, weathering and water pH).
f. Plan and conduct an experiment to investigate how abiotic factors influence organisms and how organisms influence the physical environment.
