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)

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.
