Final answer:
Chocolate agar (CHOC) is an example of enriched media, which contains additional nutrients such as vitamins and growth factors to support the growth of fastidious organisms.
Step-by-step explanation:
Chocolate agar (CHOC) is an example of enriched media. Enriched media are designed to provide the extra nutrients required by complex, fastidious organisms that have specific growth requirements. These media, like Chocolate agar, contain growth factors, vitamins, and other essential nutrients that help nourish these organisms and promote their growth.
While MacConkey agar is an example of a selective medium and EMB agar is both selective and differential, Chocolate agar does not inhibit other bacteria nor does it help to differentiate between species based on the color of the colonies or the change in the medium. Instead, it is formulated to support the growth of a wide range of organisms, by supplying the added nutrients necessary for their development.
