2) heterotroph
3) aerobic
4) anaerobic
part b
a) organism deriving metabolic energy in the absence of oxygen
b) synthesizes glucose and all their other organic compounds from inorganic carbon, supplied by carbon dioxide
c) coupling of energy generation to the oxidation of nutrients by oxygen
d) synthesizes their organic metabolites only from other organic compounds, which must be consumed

Answer & Explanation:

1) Autotroph = B) synthesizes glucose and all their other organic compounds from inorganic carbon, supplied by carbon dioxide.

2) Heterotroph = D) synthesizes their organic metabolites only from other organic compounds, which must be consumed.

3) Aerobic = C) coupling of energy generation to the oxidation of nutrients by oxygen.

4) Anaerobic = A) organism deriving metabolic energy in the absence of oxygen.
