Question

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

Explanation:

Chemotrophs are organisms that obtain energy from chemical compounds (like inorganic or organic chemicals) and use them to build or obtain matter. Consuming other organisms is for heterotrophs (like consumers), and sunlight is for phototrophs (like plants). So chemotrophs get energy and matter from chemical compounds.

Answer:

chemical compounds
