Q
Q: What is the role of Rhizobium in plant ecology?
Solution: Rhizobium bacteria form symbiotic relationships with legume roots, fixing nitrogen and improving soil fertility.
Steps: 6
Step 1: Understand that Rhizobium is a type of bacteria.
Step 2: Know that Rhizobium lives in the soil and can attach to the roots of certain plants, especially legumes (like beans and peas).
Step 3: Learn that when Rhizobium attaches to the roots, it forms a special partnership with the plant, called a symbiotic relationship.
Step 4: Recognize that this relationship helps the plant because Rhizobium can take nitrogen from the air and convert it into a form that plants can use.
Step 5: Understand that nitrogen is an important nutrient for plants, helping them grow strong and healthy.
Step 6: Realize that when plants grow better, they contribute to the soil's fertility, making it richer for other plants.
