Question

Choanoflagellates are ____.  
A) heterotrophs
B) chemoautotrophs
C) autotrophs
D) phototrophs
E) halotrophs

Accepted Answer

Choanoflagellates are known to be heterotrophs, meaning they obtain their nutrients by consuming other organisms or organic matter. They do not have the ability to produce their own food through photosynthesis (phototrophy) or chemosynthesis (chemoautotrophy), nor do they rely on salts for their nutrition (halotrophs).
