Step 1
State one method by which nitrogen is fixed in nature.
Answer
One method by which nitrogen is fixed in nature is through the process of lightning. When lightning strikes, the intense heat produces nitrogen oxides which can be absorbed by plants, converting atmospheric nitrogen into a usable form.
Another method includes nitrogen-fixing bacteria found in the root nodules of legumes. These bacteria convert atmospheric nitrogen into ammonia, a process essential for plant nutrition.
