      After primary and secondary, there is a third category of activities that falls under tertiary sector and is different from the above two. These are activities that help in the development of the primary and secondary sectors. These activities, by themselves, do not produce a good but they are an aid or a support for the production Size: KB. Phytoplankton use chlorophyll to capture light for photosynthesis, in which carbon dioxide and water are combined to produce organic matter and oxygen. In the field of ecology, this process is referred to as primary production, since the organic material produced by phytoplankton serves as food for larger organisms at sea.. Phytoplankton are important players in the global carbon g: Indian seas.

A good understanding of these processes in the Indian Ocean is of great importance in the construction of models of seasonal energy transfer and the food pyramid and for their theoretical interpretation. Such models must take into consideration the influences of the Indian Ocean monsoons, intensity of upwelling, circulation pattern, etc., and the effects of these on rate of sedimentation, secondary production and Cited by: Primary productivity in the Indian seas.

It means the primary productivity in SEC waters of South Java known be the most abundance when Eastern Monsoon occurs and decreased during Transitional Monsoon II. The value of primary productivity in SEC waters for 1 year can be seen in Table 3.

and the distribution of primary productivity in a year can be seen in Fig. : Rizky M. Utamy, Noir P. Purba, Widodo S. Pranowo, Henhen Suherman. Variation in primary productivity, measured typically as the concentration of chlorophyll in water, is a primary determinant of all biological productivity up the food web and trophic pyramid.

In this lecture you have the opportunity to explore a number of examples of how ocean productivity varies. bon back to carbon dioxide. “Net primary production” (NPP) is GPP minus the autotrophs’ own rate of res-piration; it is thus the rate at which the full metabo-lism of phytoplankton produces biomass.

“Secondary production” (SP) typically refers to the growth rate of heterotrophic biomass. Only a small fraction of the or-File Size: 1MB.

Hence, the highest biomass production rates occur in coastal upwelling zones, the lowest in open oceans regions, and intermediate rates in marginal seas.

For near shore regions, the dominant processes influencing primary productivity are river runoff, water column mixing, and turbidity. Some unique characteristics of the lin dian Ocean The Gulf is a shallow extension of the Arabian Sea.
