A

Some species, notably bacteria and plants, can grow and reproduce by utilizing inorganic sources of these essential elements

2
Q

Photoautotrophs

A

Obtain most of their energy by photosynthesis and their main source of carbon is CO2.

This catergory includes photosynthetic bacteria, algae, and plants.

3
Q

Chemoautotrophs

A

Obtain their energy by oxidizing inorganic molecules and utilizing CO2 as a carbon source.

Some bacterial species are chemoautotrophs but there are no eukaryotic examples.

4
Q

Heterotrophs

A

Heterotrophs, such as animals, need an organic carbon source.

5
Q

Photoheterotrophs

A

Photosynthetic organisms that require an organic compound as a carbon source.

6
Q

Chemoheterotrophs

A

Non-photosynthetic organisms that require organic molecules as carbon sources.
