- (D) air
- (E) survival
- (F) salt water
- (G) murky water
- (H) produce light
--
Let's think first: Organisms that live in marine biomes must be adapted to the salt in the water. Some familiar examples of biomes include tundra, desert, chaparral, and open ocean. Organisms that live in the ocean must be adapted to the salt water.... So the answer is [(F)]
