Question

many species depend on plants for their energy through photosynthesis. tube worms depend on another form of life for their energy through chemosynthesis. what form of life do tube worms depend on for their energy?
viruses
protozoans
chemosynthetic bacteria

Explanation:

Tube - worms live in deep - sea environments where there is no sunlight for photosynthesis. They have a symbiotic relationship with chemosynthetic bacteria. These bacteria convert inorganic compounds into organic compounds through chemosynthesis, providing energy for the tube - worms. Viruses and protozoans are not the energy sources for tube - worms in this context.

Answer:

chemosynthetic bacteria
