Tetraphosphorus trisulfide or Phosphorus sesquisulfide

Explanation:

The chemical name of  P4S3 is Tetraphosphorus trisulfide or Phosphorus sesquisulfide. These compund are formed when sulfur atoms are introduced into the P4 tetrahedron structure. These compounds consists of some P–P bonds and some P–S–P bridges

P4S3 is a covalent compound and following rules should be followed for determining it chemical name -

a) Name for the compound is dependent on the number of atoms  present

b) Use the prefix" tri " for 3 atoms and “Tetra-“ for four atoms.

c) put "ide" suffix in the name of last element

In the compound P4S3, there are two elements

a) Phosphorus which has four atoms and thus prefix "tetra" will be used

b) Sulphur which has three atoms and thus the prefix "tri" will be used  and suffix "ide" will be used

So the name becomes "tetra" phosphorus "tri"sulf "ide" which can be read as Tetraphosphorus trisulfide

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
