Question

Carla is reading an article about a certain species of bacteria that can grow on the leaves of common house plants. The article explains that the bacteria are heterotrophic.
Which is best supported by the information in the article?

The bacteria are probably eubacteria because they live on common plant leaves.
The bacteria could be either eubacteria or archaebacteria because both types are always heterotrophic.
The bacteria must be eubacteria because they are heterotrophic.
The bacteria could be either eubacteria or archaebacteria because both types can live on plant leaves.

Answer 1

Answer:

The bacteria are probably eubacteria because they live on common plant leaves

Explanation:

Answer 2

The bacteria are probably eubacteria because they live on common plant leaves.

Archaebacteria living in extreme places(like the thermophile bacteria that in a volcano) while eubacteria lives in normal places. Leaves of common houseplants is not an extreme location, so Archaebacteria is less likely found there. Both eubacteria and archaebacteria could be autotroph or heterotroph, so the information cannot be used to conclude anything.
