The extremely low organic production, or oligotrophy, of the offshore waters of the Levantine Basin is manifested in the extreme transparency of the water, measured by the disappearance of a Secchi disc at
Web12 sep. 2024 · A popular method for measuring productivity in a factory setting is to compare total labor time, which is also called the input, with the number of products manufactured, or the output. By doing so, companies can calculate a ratio that shows them how efficiently their employees are working. How do you calculate NPP and GPP? WebAt the scale of the ecosystem, most of this energy comes from sunlight, which is converted into the energy of organic matter in living biomass through the process of primary production, and from imports of organic matter from adjacent ecosystems. This import of energy in organic matter is, of course, dependent upon primary production in the ...
