definition of marine ecosystem

Many of the worlds habitats and ecosystems depend on a delicate balance of rainfall, temperature and soil type. A complex food chain supply exists based on these factors. Higher temperatures and precipitation changes are likely to cause diverse changes such as increased forest susceptibi..

Living organisms cannot live isolated from their non-living environment. Living and the non-living environment interact with each other to form a stable system. A natural self-sufficient unit of the world comprising a biotic community (living organisms) and its abiotic physico-chemical environment..

These are fish that are sustained in salt-water bodies like seas and oceans. This requires mechanisation. Fishing trawlers fitted with sophisticated electronic fish locating equipment are used for deep-sea fishing. Some marine fish are Bombay duck, Catfish, Mackerels, Red mullet, Sardine ..
