Students will learn about the mutualistic relationship between plants and nitrogen fixing bacteria. The effect of environmental conditions on this relationship will be investigated in two inquiry activities.
At the conclusion of the lesson, students will be able to:
- Define mutualism.
- Describe the mutualistic relationship between nitrogen fixing bacteria and legumes. (biotic interactions)
- Describe how changing environmental conditions can alter the relationships between organisms. (abiotic interactions)
