Answer 3

into the soil and air during decomposition

Question 4

Role of Nodule bacteria and Free living soil bacteria

Answer 4

they take Nitrogen and convert it into Nitrates

Question 5

role of Nitrifying bacteria

Answer 5

take ammonia into Nitrites and that can be absorbed by plants

Question 6

Role of Denitrifying bacteria

Answer 6

take Nitrates into N2

Question 7

what maintains the balance of O2 and CO2

use CO2 for photosynthesis and release 02
Algae produces more than 50%

Question 8

Answer 8

they live in the roots of the legumes
they absorb nitrogen and convert them into Nitrates so plants can absorb the N2
in return they get Carbohydrates, from the legume

Question 9
