What will happen if nitrogen fixation doesn't take place?
The effect would be disastrous as amajor biogeo chemical cycle-nitrogen cycle will be disrupted.
The possible effects-
1)the plants would die out soon as after the soil is exhausted of the nitrogen in the soil,plants wouldn't grow as the plants wouldn't be able to take in nitrogen .The soils won 't grow,the land would be barren.
2)as this would happen(plants not growing)animals having a diet of plants(herbivores)would die as there was nothing which they could eat and they would die out.
3)this would further disrupt the ecosystem and carnivores animals too,would soon die out as a large proportion of their prey would die out.Further more other animals (not herbivores) would end up dying in large numbers due to desperation of the carnivores animals.(the weaker carnivores would die)Finally all animals would die.
4)this would ultimately affect the humans as they too can' t survive without other organisms.
In short ,Life on earth would end as the ecosystem will be ruptured.
