Question

where do chemotrophs get their energy and matter? chemical compounds they consume other organisms sunlight

Explanation:

Chemotrophs are organisms that obtain energy by oxidizing chemical compounds (either organic or inorganic). They do not rely on sunlight (which is for phototrophs) or consuming other organisms in the way heterotrophs that "consume other organisms" do. So the correct source of energy and matter for chemotrophs is chemical compounds.

Answer:

A. chemical compounds
