Marine life asexually by binary fission, fragmentation, or budding; unlike bacteria and eukaryotes, no known species forms spores. Archaea are particularly numerous in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet. Archaea are a major part of Earth's life and may play roles in both the carbon cycle and the nitrogen cycle. Of eukaryotic groups, the protists are most commonly unicellular and microscopic. This is a highly diverse group of organisms that are not easy to classify. Several algae species are multicellular protists, and there are marine slime molds have
Short food supply chains proximate, extended. Face to face are characterized by physical encounters between producers and consumers (as in the case of farmers' markets). In the proximate short food supply chains producers are not necessarily managing product distribution (as in the case of consumers' cooperatives). In the extended short food supply chains, although geographical distances between producers and consumers may be long, consumers are aware of the identity of the producers and of the products (such as in the case of fair trade and protected denominations of origin).
