I have some questions that relate to table 2.1 which lists the chemical elements that occur naturally in the human body. Similar percentages of these elements are found in most living organisms.

a. In what abiotic (non-life) chemical forms are these elements often found in nature?

I was thinking soil for this one.

b. In what chemical form do animals need to obtain these elements?

I was thinking magnesium

c. In what chemical form do plants need to obtain thse elements?

I was thinking water and soil

I am really not sure, I am having a hard time understanding the question.
