- mineral fertilizers

These sources all add to the phosphorus found in soil in both organic or inorganic forms.

2. <u>Phosphorus</u> from soil is released to (red arrows):

- <u>organic phosphorous</u> through:

<em> -->plant uptake</em> in the form of soluble P. This soluble form has several of its own sources such as primary minerals,  mineral surfaces, secondary compounds etc.

--> <em>immobilization</em> where microorganisms convert and absorb inorganic P

- <u>phosphates in solution</u> through:

-->runoff and erosion

-->a small portion though leaching

Which type of macromolecule makes up the capsid of a virus
Elenna [48]

Protein

Proteins are the most versatile macromolecules in living systems and they play important roles in essentially all biological processes. Protein makes up the capsid of a virus. The infective extracellular form of a virus known as a virion contains at least one unique protein synthesized by specific genes in the nucleic acid of that virus. In almost all viruses, at least one of these proteins forms a shell (called a capsid) around the nucleic acid. Certain viruses also have other proteins internal to the capsid. Some of these proteins act as enzymes during the synthesis of viral nucleic acids.
