Question

2. How are the kelp and the chemosynthetic bacteria of the
hydrothermal vents similar?
A. Both use energy from the sun to make food.
B. Both are primary producers.
C. Both are scavengers.
D. Both use hydrogen sulfide as an energy source.

Answer 1

Answer:

C. Both are primary producers.(THIS IS THE CORRECT ANSWER)

Explanation:

Answer 2

Chemosynthesis is a biological conversion of carbon molecules. These are found around the hydrothermal vents.

• It is due to the bacteria feeds on the hydrogen sulfide that is coming out from the vents that are required as an energy tonic for the bacteria to survive and kelp also has similar requirements.

• Kelps forests are shelters for these bacteria and hence both are found near the source of energy.  

Hence the option B both are primary producers.
