Include marine animals, marine plants, microorganisms and viruses, wherein marine animals include invertebrates and vertebrates. Invertebrates include various snails and shellfish. Vertebrates include all kinds of fish and large marine animals.
Marine animals: sharks, whales, jellyfish, etc.
Marine plants: kelp, Undaria pinnatifida, antlers, kelp, Sargassum, etc.
Marine microorganisms: Compared with land, the marine environment is characterized by high salt, high pressure, low temperature and nutrient dilution. Marine microorganisms have already adapted to the complex marine environment and have their own unique characteristics.
Extended data:
There is also a small part of chemical energy extracted from the marine microbial picture collection? Cultured bacteria are producers in deep-sea biological communities. Marine bacteria will pollute hydraulic structures, and under certain conditions, its metabolites, such as ammonia and hydrogen sulfide, will also poison the aquaculture environment, thus causing economic losses in aquaculture.
However, the antagonism of marine microorganisms can destroy terrestrial pathogens, and its great decomposition potential can purify almost all kinds of pollution, and may also provide new biological resources such as antibiotics. Therefore, with the progress of research technology, marine microorganisms are paid more and more attention.
Marine viruses: Marine viruses are diverse, with morphological diversity and genetic diversity. The density distribution of marine viruses in seawater is high near shore and low far shore; It is abundant in the marine light-transmitting layer, gradually decreases with the increase of seawater depth, and tends to increase in the water layer near the seabed, and its density can sometimes reach 10 6 ~ 10 9 virus particles (VPS)/ml. It is 5~ 10 times higher than the bacterial density.
