Cowhich best describes the cell theory

As technological advancements are made, the cell theory may change. The more advancements we have and create, we are able to learn more about cell theory. The new advancements are able to help us more with the absolute knowledge of cell theory in a whole

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.
