Question

organisms living near hydrothermal vents depend on a process bacteria use to convert sulfur and other chemicals into chemical energy is called * 5 points
nutrient chemosis
hydrosynthesis
chemosynthesis
photosynthesis

trenches form at * 5 points
subduction zones
transforming boundaries
diverging boundaries
slab pulls

Explanation:

1. Organisms near hydrothermal vents rely on chemosynthesis. Bacteria use this process to convert sulfur - containing and other chemicals into chemical energy. Photosynthesis requires light and is not applicable here. Nutrient chemosis and hydrosynthesis are not the correct terms.
2. Trenches form at subduction zones. At subduction zones, one tectonic plate is forced beneath another, creating deep - ocean trenches. Transforming boundaries are associated with faults, diverging boundaries create mid - ocean ridges, and slab pulls are a mechanism related to subduction but not the location of trench formation.

Answer:

1. C. chemosynthesis
2. A. subduction zones
