Do you think the human population will continue grow exponentially ? why or why not?

yes they will present there on earth but not sure about growing exponentially because extinction and natural hazards can reduce population drastically. As we know that many extication happened and gone but still the earth has life and humans are the most advanced animals and they have every skill to survive so i think they will survive on earth even the extinction occurs human will be preferred to be alive than any other species

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
