Nanophytoplankton Nanophytoplankton Nanophytoplankton are particularly small phytoplankton with sizes between 2 and 20 µm. They are the autotrophic part of nanoplankton. Like other phytoplankton, nanophytoplankton are microscopic organisms that obtain energy through the process of photosynthesis and must therefore live in the upper sunlit layer of ocean or other bodies of water. These microscopic free-floating organisms, including algae, and cyanobacteria, fix large amounts of carbon which would otherwise be released as carbon dioxide.. The term nanophytoplankton is derived from the far more widely used term nannoplankton/nanoplankton. Phytoplankton form the beginning of the food chain for aquatic animals. Zooplankton and krill feed
Short food supply chains can develop autonomous marketing strategies based on differentiation. These strategies give farmers the possibility of keeping a bigger share of the value added within the farm and within the local economies. Given these characteristics, short food supply chains are increasingly taken into consideration by rural and food policies as a driver of change in the food system and a policy tool for rural development. The analysis of short food supply chains has fed a broader debate on "alternative food chains", "alternative food networks", and "sustainable food chains". SFSCs are considered the most appropriate channels for organic and locally specific products
