During the moss life cycle, there is an alternation of generations, between saprophyte and gametophyte. the sporophyte has the diploid or 2n chromosome number while the gametophyte is haploid or n. what process produces the 2n sporophyte in the moss life cycle?

the correct answer is fertilization

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
