Marine life, however, has to be adapted to living in a habitat with a high concentration of salt. It is a weak solution of mineral salts and decayed biological matter. The marine food chain starts with the tiny phytoplankton – unicellular organisms such as algae that produce their own food via photosynthesis. The types of ecosystems found in this biome are oceans, coral reefs, and estuaries; all are saltwater environments. The primary flora in this zone is seaweed.
