chemically, agar is a galactan, a complex carbohydrate with galactose molecules which are not metabolized by non-ocean microbes.
*** It has been know that only marine bacteria can degrade agar, but there are some reports that some soil bacteria can degrade and utilize the agar. http://www.jstage.jst.go.jp/article/bbb/67/5/67_1048/_article/-char/en
Mannitol Salt Agar Complex is a synthetic medium because it is prepared from pure chemical substances and the exact composition of the medium is known.
The composition of luria agar is NaCl,Trypotone, Yeast extract and agar.
Spirit blue agar contains peptone, yeast extract, lactose, agar, and spirit blue dye. The dye is added to visualize the digestion of lactose by bacteria, allowing for the differentiation of lactose-fermenting and non-fermenting organisms.
Agar is a chemical obtained from brown algae . It is actually a solidifying agent and used to prepare media for microbial growth .
The chemical composition remain unchanged.

Malt extract agar typically consists of malt extract, agar as a solidifying agent, and may also contain additional nutrients like peptone or yeast extract. The exact composition can vary depending on the manufacturer or specific recipe used.

Spirit blue agar contains peptone, yeast extract, lactose, agar, and spirit blue dye. The dye is added to visualize the digestion of lactose by bacteria, allowing for the differentiation of lactose-fermenting and non-fermenting organisms.
It's a differential agar used to differentiate between lactose fermenters and non-lactose fermenteing bacteria.

The chemical composition remain unchanged.
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
i think is chemical composition its not chemical composition, it's how they were formed

Yes, the composition of the rocks is as a result of the distinct chemical composition.
