Question

Match each term with the appropriate description of the organism. Some terms will not be used: Requires pre-formed carbon compounds made by other organisms. ________ Requires oxygen for metabolic processes. ________ Able to obtain energy directly from sunlight.________ Requires an oxygen-free environment. ________ Able to use CO_2 to generate all needed carbon compounds.______ Prefers an oxygen-free environment, but is not required. ________ Obtains energy from oxidation of chemical fuels. _________ Can survive with or without oxygen, but prefers to use oxygen. ____ Xerophile Aerobe Mesophile Acidophile Obligate anaerobe Heterotroph Halophile Phototroph Thermophile Autotroph Facultative anaerobe Chemotroph Aerotolerant Cryophile (Psychrophile) Piezophile (Barophile)

Explanation / Answer

a-Heterotroph

b-Aerobe-require oxygen energy source from the from carbohydrates (sugars)

c-Phototroph- uses energy from sunlight to synthesize organic compounds

d-anaerobic do not need oxygen to survive

e-Autotroph or producer which produces complex organic compounds

f-Aerotolerent-Do not use oxygen for the survival but can tolerate small amount of oxygen when present in the environment.

g-Chemotrophs-Obtain their energy from chemicals (organic or inorganic compounds)

h-Facultative aerobes-can grow with or without oxygen because they can metabolise energy aerobically or anaerobically
