if the alge wasnt there then the fishes wouldnt have anything to eat and and if the fishes die out because they dont have food the the shark population will decrease because it will have less eating option.
limiting factors in the ocean are sunlight - heat - water - temperature - oxygen.
if the sea turtles were not their then the great white shark population would decrease because theit would would be a lot of competition
examples of energy roles is when the phytoplankton gets eaten by the small crustaceans and the they get eaten by the herring by the mackerel then they get eaten by the the shark
food webs / food chains
a food wab is more realstic than a food chain because a food web show the energy that can go from one organizm tp antother
if you take away the penguin the leopard seal will have one less source of energy

the plant needs sunlight to be able to go throw the photosynthesis the photosynthesis happens inside the leaf
because of tropism the plant goes striaght up because its going for the sun.if the didnt go up for the sun they wouldnt have sunlight and it wouldnt be able to grow
a example of decomposers or algae they eat all the dead fish and make them into nutrant for the ocean floor
a adaptation for the fish is for it to have gills so it will be able to breath under water
if the fish didnt have gills then they will not be able to breath under water
natural selections are the way that the fish has his color so it can blend in with its background
