Nitrate present in the soil is also reduced to nitrogen by the process of denitrification it is carried out by
1 Pseudomonas
2 Thiobacillus
3 Rhizobium
4 Both (1) and (2)
Explanation:
Nitrate present in the soil is also reduced to nitrogen by the process of denitrification. Denitrification is carried by bacteria Pseudomonas and Thiobacillus.

Plants compete with microbes for the ____ nitrogen that is available in soil.
1 Abundant
2 Unlimited
3 Limited
4 None of the above.
Explanation:
Plants compete with microbes for the limited nitrogen that is available in soil. Thus, nitrogen is a limiting nutrient for both natural and agricultural eco-systems.

What is considered as nitrogen fixation?
1 Conversion of ammonia into nitrogen
2 Conversion of amino acids into nitrogen
3 Conversion of nitrogen into ammonia
4 All of the above.
Explanation:
The process of conversion of nitrogen \(\left(\mathrm{N}_{2}\right)\) to ammonia is termed as nitrogen fixation.
