Answer 14

animals, protozoa, fungi, bacteria, archaea

Question 15

Photosynthetic organisms.

Answer 15

Photoautotroph (ie. Plants, algae, some bacteria and protozoa)

Question 16

Photosynthetic bacteria that use organic acids as a carbon source.

Answer 16

Photoheterotroph

Question 17

Animals, most protozoa, bacteria, and fungi

Answer 17

Chemoheterotroph

Question 18

Possibly the most numerous organisms on the planet.

Answer 18

Chemoautotroph (i.e. archaea)

Question 19

The minimum and maximum temperature for an organism where an enzyme can function and a microbe can grow.

Answer 19

Range

Question 20

Where the microbe grows best

Answer 20

Optimum (enzymes are working the fastest and most efficiently)

Question 21

O2 must be present for these microbesto function.

Answer 21

Obligate Aerobes

Question 22

These microbes can live with or without O2.

Answer 22

Facultative Anaerobes

Question 23

These microbes cannot live in the presence of O2 because they do no have superoxide dismutase or catalase.

Answer 23

Obligate Anaerobes
