Question

Some bacteria live in the roots of plants like soybeans and peas. What is the role of these bacteria in the nitrogen cycle?

Answer 1

Answer:

Bacteria's main role in the nitrogen cycle is to be able to convert the nitrogen gas from the atmosphere into nitrates, so plants can use them.

Explanation:

The main steps involved are decomposition, nitrification, nitrogen fixation and denitrification.

In decomposition, bacteria in the soil breakdown the protein and urea in dead plants and animals into ammonium.

In nitrogen fixation, there are two different types of bacteria. One type is in the soil and the other type can be found in the roots of some legume plants.

These bacteria can directly 'fix' the nitrogen gas from the atmosphere and convert it into ammonium.

In nitrification, nitrifying bacteria can convert this ammonium into nitrites and then into nitrates.

These can then be used by plants from the soil.

Finally, denitrifying bacteria convert nitrates in the soil back into nitrogen gas so we are back at the beginning of our cycle. This only happens when there are anaerobic conditions (when there is no oxygen).

Answer 2

The bacteria has nitrogen fixation properties, and helps to make soil fertile.

Explanation:

• Nitrogen plays an important role in the living world by the bacteria and other single-celled organisms that converts the atmospheric nitrogen into biologically usable form while others live inside the plants.

• They convert it into ammonia that can be used by the pants an example of this if we add half of the nitrogen to the green peas they will grow taller and another component is the phosphorus that limits the nutrient in both the natural ecosystem and agriculture.
