Answer is Divides protostomes into 2 taxa.

Refer below.

Explanation:

Consider the two phylogenetic hypotheses regarding the relationships of the animal phyla. The tree that is based on molecular evidence differs from the tree based on morphological evidence in that it:

Divides protostomes into 2 taxa

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.
