Marine life live in the water column of large bodies of water and that cannot swim against a current. They provide a crucial source of food to many large aquatic organisms, such as fish and whales. These organisms include drifting or floating bacteria, archaea, algae, protozoa and animals that inhabit, for example, the pelagic zone of oceans, seas, or bodies of fresh water. Essentially, plankton are defined by their ecological niche rather than any phylogenetic or taxonomic classification. Though many planktonic species are microscopic in size, "plankton" includes organisms covering a wide range of sizes, including large organisms such as jellyfish. The
Short food supply chains Short food supply chains Short food supply chain (SFSCs) is a broad range of food production-distribution-consumption configurations, such as farmers' markets, farm shops, collective farmers' shops, community-supported agriculture, solidarity purchase groups. More in general, a food supply chain can be defined as "short" when it is characterized by short distance or few intermediaries between producers and consumers. SFSCs were originally identified as examples of "resistance" of farmers to modernization of the food system, characterized by the development of supply chains based on long-distance trade. Resistance consists in the fact that, by selling directly to consumers, farmers bypass intermediaries and thus
