In the blue water there are many food chains. These food chains are different from each other .Most of the food chains begin with seaweed "kelp and read algae". Urchins eat kelp whereas krill eat read algae. Urchins are eaten by sea otters but krill's are eaten by mackerel. The killer whale eagles and fisherman are at the top of food chains.
