Answer:

the rate at which soil bacteria perform nitrogen fixation

Explanation:

Plants cannot use nitrogen in the air directly as nitrogen present in the air cannot react with other compounds. Nitrogen present in the air is converted into ammonia so that the plants can utilize it. The nitrogen-fixing bacteria convert the atmospheric nitrogen into ammonia.

<em>When the same crop is grown again and again on a soil, the resources become depleted in the soil. Also, the number of nitrogen-fixing bacteria decreases. </em>

Hence, it is essential to practice crop rotation.

  • The height of the sea as measured along the shore in relation to a particular place on land is what tide stations all around the world tell us about what is happening locally.
  • NASA uses satellites to measure sea level all over the world.
  • Height of the ocean's surface, often known as sea level, is measured by the Jason-3 satellite using radio waves and other equipment.
  • It studies how the global sea level is changing over time for the entire Earth every 10 days.
  • The average sea level is 6,371.001 km (3,958.756 mi), and it is 6,356.752 km (3,949.903 mi) at the poles.
