What Type of Organism Would You Expect to Find Living

Question

What type of organism would you expect to find living at deep sea vents?
A) Carnivores
B) Chemo-autotrophs
C) Grazers
D) Chemo-heterotrophs

Accepted Answer

Deep sea vents are known for supporting a unique ecosystem that relies on chemosynthesis rather than photosynthesis. Chemo-autotrophs, such as certain types of bacteria and archaea, are able to use the chemical energy from sulfur, hydrogen, and methane compounds released by the vents to produce organic compounds. These chemo-autotrophs then serve as the base of the food chain, supporting other organisms like tube worms, crabs, and fish that live around the vents.
