A chemically defined media is a media in which the chemical nature of all the ingredients and their amounts are known. These media are also called synthetic media, mainly chemoorganotrophic heterotrophs also can be grown in defined media with glucose as a carbon source and an ammonium salt as a nitrogen source.
No, it cannot. Defined media can only consist of pure chemicals added together. Since yeast extract is a digest of yeast, there is no way of knowing exactly what chemicals it contains. Substitutions in defined media typically consist of a carbon source (i.e. xylose) and any amino acids the sample requires.
Complex media are preferable for routine cultivation of microorganisms than chemically defined media because it provides highly enriched sources such as plant or animal extracts, vitamins, minerals, protein, sugar, and or blood to the organism, supplying them specific nutritional substances needed for their growth. Chemically defined media on the other hand does not supply such a vast abundance of nutritional substances.
Sabouraud Agar is used as a selective media to isolate yeasts and molds. generally, use a complex kind of media, involving plant or animal extracts.
definition of simple media
Complex culture media is a type of nutrient for growing bacteria that does not have exact composition. For example it may contain beef broth which has many nutritional components but the exact ratio of each component is not known. The opposite would be defined medium which contains exact amount of specific nutrients.
Chemically Composition is known & made with synthetic inorganic chemical substances.. Eg:- Glucose Broth, Inorganic Synthetic Broth
In the complex media you have unknow compounds mixed in wheras; in the defined media you know all concentrations of the compounds in the media
Because complex media contain all nutrients, both known and unknown, which may be required for optimal growth of a wide variety of bacteria.

because fastidious organisms require specific nutrients that can not be supplied to them in the chemically defined medium therfore dont grow as well

Old media is newspapers.
By definition, any story told using film or digital media is called a film. Film is also defined as a celluloid medium used for the purpose. A film is also called a movie, which doesn't have another definition.
