___ 14- An organism that uses lactose as a source of electrons, as an energy source, and as a carbon source is an example of a:
A) fotolitoautotrofo
B) photoorganoheterotrofo
C) quimiolitoautotrofo
D) chemolitheterotrofo
E) chemoorganoheterotrofo
___ 15- An organism that uses H2S as a source of electrons, sunlight as an energy source, and CO2 as a carbon source is an example of a:
A) fotolitoautotrofo
B) photoorganoheterotrofo
C) quimiolitoautotrofo
D) chemolitheterotrofo
E) chemoorganoheterotrofo


___ 16- An organism that uses ammonium as a source of electrons, H2S as an energy source, and CO2 as a carbon source is an example of a:
A) fotolitoautotrofo
B) photoorganoheterotrofo
C) quimiolitoautotrofo
D) chemolitheterotrofo
E) chemoorganoheterotrofo
___ 17- An organism that uses glucose as a source of electrons and a source of carbon, sunlight as an energy source, is an example of a:
A) fotolitoautotrofo
B) photoorganoheterotrofo
C) quimiolitoautotrofo
D) chemolitheterotrofo
E) chemoorganoheterotrofo

Explanation / Answer

1- D

Chemolithoorganotrophs

since source of electrons is Ammonium which is chemotropic, and H2S is energy source, hence Lithotropic and glucose a carbon donour which is an organic compound

14-B

Here source of electrons is an organic compund, light is source of energy and organic molecule a source of carbon therefore nutrition is PHOTOHETEROTROPHIC.

15-A

PHOTOAUTOLITHOTROPHS

Light is source of energy, inorganic source of electrons, CO2 is primary C source

16- C

Organism has Chemical source of energy, inorganic source of electrons, CO2 is primary C source. Therefore nutrition is Chemolithoautotrophic

17- B

Organism has Light is source of energy, organic source of electrons, organic compounds are primary Carbon source, therefore nutrition is PHOTOORGANOHETEROTROPHIC
