BI 211.


Emphasizes transformations of energy and matter, systems level biology, and the structure and function of ecosystems. Studies the interrelationships between all forms of life and their environment. Emphasizes aspects of plant morphology and physiology that influence ecosystem function. Designed for majors in life sciences as well as those pursuing botany. Field Trips may be required.

Learning outcomes

1. Use multiple representations to model the relationships between species/population abundance and distribution in relation to biotic and abiotic factors.
2. Describe the flow of energy and the cycling of matter in ecosystems in the biosphere at human and geologic time scales.
3. Explain how biotic and abiotic interactions influence and are influenced by morphological, physiological and behavioral traits.
4. Generate questions, construct testable hypotheses about biological mechanisms based upon observations of the natural world, and effectively communicate experimental outcomes using professional scientific formats.
5. Apply quantitative skills to biological problems including interpreting charts and graphs, applying mathematical and algebraic concepts to biology, and identifying trends in data.
6. Reflect on the impact of biological research on society.

Required materials

May require access to a computer and internet, a textbook and/or coursepack.

Grading methods

Grades will be determined by unit exams and lab reports including at least one journal-style formal lab report; optional grading methods include homework assignments, in-class activities, and lab practical exams.
