Botany 431 - Physiological Plant Ecology
At the end of your study this week, you should be able to achieve the objectives listed below. You must assemble the evidence that you have achieved these learning outcomes into your Portfolio. You should provide evidence that would be regarded as performance at the top two levels of Biggs' SOLO Taxonomy.
The material in your Portfolio will be assessed as Project 3.
If you wish to discuss this material informally with your peers, you can interact in
Esme's Coffee Shop.
You can also challenge your peers by posting questions for them to respond to on the
Student Quiz Board.
When you have completed this section you will be able to:
- Recall from Botany 240, the mechanism by which atmospheric dinitrogen is reduced in the Legume-Rhizobium association.
- Evaluate the ecological roles played by free living organisms and associations capable of fixing atmospheric nitrogen.
- Discuss typical patterns of nitrogen partitioning around annual plants through their life cycles.
- Evaluate the impact of human activity on the cycling of nitrogen.
