  1. Nitrogen

  2. Potassium

  3. Sulphur

  4. Ammonia

Show answer
Correct Option: D
Explanation:

Nutrients obtained by plants and animals are classified into two groups organic and inorganic. Inorganic nutrients are those that are not easily found in animals or plants. They are always converted into their organic forms. Ammonia is an organic nutrient generally found in animals for synthesis of various metabolite.

Fertilizers supply this component that is essential for plant growth. Name the component.

evs deficiency diseases need for nutrients nutrients needed by the body balanced diet and malnutrition food for health nutrition and its deficiency nutrition and its need

  1. Carbon

  2. Calcium

  3. Nitrogen

  4. Potassium

Show answer
Correct Option: C
Explanation:

Nitrogen is one such element which is very important in plant growth because it is an essential part of the chlorophyll that is the site of photosynthesis.

Nitrogen is not found in the free state in the soil and the plants cannot take up nitrogen from the air directly so we add fertilizers that are rich in nitrogen and supply the plant with it.
Calcium and potassium are trace elements and are needed in small amounts and can be taken up from the soil. Plants take up carbon directly from the atmosphere.
So, the correct option is 'Nitrogen'

Plants require nitrogen along with carbohydrates. This nitrogen can be obtained by

  1. Rhizobium

  2. Vibrio

  3. Salmonella

  4. Felix

Show answer
Correct Option: A
Explanation:

Rhizobium is a nitrogen-fixing bacteria found in symbiotic association with the root nodules of leguminous plants. 

For nitrogen fixation rhizobium needs an oxygen-free environment because oxygen acts as a poison and so it forms the association because the root nodules contain leg hemoglobin which is an oxygen scavenger. 
In return the plant gets Nitrogen.
So, the correct option is 'Rhizobium'
