Question

which would be a habitat for chemoautotrophs but not photoautotrophs? a) deep ocean trench b) shallow ocean water c) high - altitude mountain d) cold tundra plain

Explanation:

Photoautotrophs require light for photosynthesis. Deep - ocean trenches have little to no light, making them unsuitable for photoautotrophs. Chemoautotrophs can use chemical energy sources and can thrive in such environments. Shallow ocean water, high - altitude mountains, and cold tundra plains have access to sunlight which supports photoautotrophs.

Answer:

A. deep ocean trench
