Why is the activity of the deep-sea fishes so low? Due to the poor level of photosynthetic light reaching deep-sea environments, most fish need to rely on organic matter sinking from higher levels, or, in rare cases, hydrothermal vents for nutrients. This makes the deep-sea much poorer in productivity than shallower regions.
Why is there less life in the deep sea? Without sunlight, photosynthesis, the process by which plants make food, is not possible; this contributes to a general scarcity of food in the deep ocean and thus a lower overall density of organisms in many parts of the deep ocean.
Why are deep sea organisms very often slow growing? Lack of resources. At this depth, there is not enough light for photosynthesis to occur and not enough oxygen to support animals with a high metabolism. To survive, creatures have slower metabolisms which require less oxygen; they can live for long periods without food.
What are the primary challenges to fishes living in the deep ocean? Fish find it hard to live in this zone, as there is crushing pressure, cold temperatures of 4 °C (39 °F), a low level of dissolved oxygen, and a lack of sufficient nutrients.
