The majority of water molecules moving across plasma membranes by osmosis do so via a process that is most similar to a) simple diffusion b) a process that requires energy from the cell c) active transport d) facilitated diffusion e) cotransport.

The answer is a) simple diffusion.

Explanation:

Osmosis is more similar to simple diffusion due to the fact that it doesn't require a protein or channel to facilitate its movement through the membrane. Also, it doesn't require any energy, but it does mostly depend on a chemical, or sometimes electrical, gradient.

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.
