The distribution of the earth’s diversity and the abundant life widely shaped by the patterns of the vegetation growth both on the land and the water bodies — these patterns are known as the net primary production (NPP). NPP refers to the rates in which vegetation converts water and carbon dioxide to be energy compounds rich in carbon. The tropical rainforests the biggest producers in the whole ecosystem due to their longitudinal gradient. However, with regards to marine productivity, the NPP is more significant in the high latitude water bodies found around the poles. Basing the research on direct measurements signify that the NPP in the tropical rainforests bears no difference to the yearly NPP located in the temperate forest (Houston & Wolverton, 2009). A paradox exists on the determination of the highest producer of NPP and to resolve this a proper reexamination of the terrestrial productivity gradient to be able to obtain the overall global distribution of the production and understand the patterns of distribution.
The study uses the various ecosystems to identify the production levels as per each ecosystem. Terrestrial, the grasslands, forests, and aquatic ecosystems each adopt different techniques to determine the NPP and the gross net production. Mapping and satellite imaging gives the readers a proper monitoring tool for carbon metabolism; reference to data from NASA’s Terra cable and the Moderate Resolution Imaging Spectroradiometer (MODIS). In the mid-latitudes, seasonal changes affect production- peaking during each hemispheres’ several summers. The tropics have variations across the year, drier seasons being productive (Houston & Wolverton, 2009).
Understanding the universal circulation of net manufacture is vital to the existence of various living organisms. However, there is difficulty in quantifying the correct numbers of distribution due to the various natural factors. Estimation using multiple proxies does, however, provide a blurry result, which is parallel to the actual results.
