Questions & Step-by-Step Solutions
What is the primary benefit of using nitrogen-fixing bacteria in agriculture?
Correct Answer: Nitrogen-fixing bacteria help in converting nitrogen from the air into a usable form for plants.
Step 1: Understand that plants need nitrogen to grow.
Step 2: Know that nitrogen is often found in the air, but plants cannot use it in that form.
Step 3: Learn that nitrogen-fixing bacteria can take nitrogen from the air and change it into a form that plants can use.
Step 4: Realize that by using these bacteria, farmers can help plants get the nitrogen they need without using chemical fertilizers.
Step 5: Conclude that the primary benefit of using nitrogen-fixing bacteria is to improve plant growth while reducing the need for chemical fertilizers.
