Marine Primary Productivity: Measurements and Variability
... Primary productivity is the amount of plant tissue build up by photosynthesis over time. It is so called because photosynthetic production is the basis of most of marine production. It is worth to mention here that there are other types of primary production that are carried out by bacteria capable ...
