Describe the differences in the abiotic factors of the open ocean photic zone compared to the open ocean aphotic zone.

Photic zone refers to the upper layer of a water body described by the depth to which sufficient sunlight can penetrate to allow the process of photosynthesis. The abiotic factors, which influences the photic zone are obtainability of light and depth of the photic zone, stratification, temperature, nutrients, salinity, and currents and tides.  

The aphotic zone refers to the part of an ocean or lake where there is no or little sunlight. It is usually illustrated as the depths beyond which less than one percent of sunlight goes through. Bio-luminescence is only light found in this zone.  

The majority of the food in this zone comes from dead organisms falling to the bottom of the ocean or lake from the overlying waters. The depth of the aphotic zone is highly affected by the factors, like a season of the year and turbidity.  

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
