Your friend is a vegetarian who consumes large quantities of soy products in the place of meat. From a nutrition perspective, your friend is at risk of developing protein and iron deficiency.

Explanation:

Meat has some nutrients that may be lacking in ailments like soy. Some substances are better absorbed by animals, for example proteins and iron.  Vitamin B12,  a type of protein,  is needed for the production of DNA, and it is absent in soy. Vitamin D is important for calcium absorption  but soy products don't contain this. Finally meat products have two forms of iron heme and nonheme and Plants contain nonheme iron only. The heme iron is the most easily absorbed.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
