Answer 1

A. Psychrophiles: Responsible for food spoilage in the refrigerator (as they can grow in the lower temperature of refrigerator and they can cause food spoilage there) (C).

B. Mesophiles: Make up the normal flora of human skin (as they grow optimumly in between 35 to 40oC)(B).

C.Thermophiles: Responsible for pneumonia and strep throat (as an example Streptococcus thermophilus can do that)(F).

D. Hyperthermophiles : Forms endospores that cause botulism (Clostridium botulinum forms endospore and causes botulism disease)(A).

E. Halophiles: Not ever associated with human disease(E).

F.Acidophiles: Survive at a pH of 4.0 (because the pH 4.0 designates extreme acidic environment)(D).
