b. heterotrophs; co2
c. phototrophs; co2
d. heterotrophs; glucose
e. autotrophs; glucose

Answer 1

The answer to this question is a.

Answer 2

Plants are classified as autotrophs because they use carbon dioxide (CO2) for their carbon source.

AUTOTROPHS:

• Autotrophic organisms are organisms that are capable of synthesizing their own food using energy from sunlight (photosynthesis) or chemicals (chemosynthesis).

• Autotrophic organisms play a vital role in an ecosystem as they initiate the flow of energy from organism to organism.

• Green plants, as an example of autotroph, make use of light as an energy source and carbon dioxide (CO2) as a carbon source to make glucose (food).

• Therefore, plants are classified as autotrophs because they use carbon dioxide (CO2) for their carbon source.
