reefs #ecosys


fish(salmon, koi, angelfish, clownfish)

coral (lettuce, elkhorn, great star coral)

plants (seaweed)

sharks (whitetip, carribbean reef shark)



salt water

sunlight which makes it all the way down to to sea floor



Carrying Capacity

they all need water, shelter ,and food

clown fish in the reefs have a very special relationship with the anemone and are very special to them. They are a large help to the anemone as they clean the anemone by eating the algae and other food leftovers on them. Their food is the food leftovers and algae fro the anemone which include copepods ,isopods ,and zooplankton.

Limiting Factors




Predator/prey relationship

tiger shark and a green sea turtle

tiger sharks can grow up to 25 feet long and the green sea turtles only protection is their shell. I would think that they both would be able to ketch most diseases and they would both be affected b the pollution in the water.

Energy Roles

coral - marine inveriebrates - autotrouphs - level 100%

clown fish - fishes from the subfamily - primary consumer - level 10%

stingray - cartilaginous fish related to sharks - secondary consumer - level 1%

shark - cartilaginous skeleton - tertiary consumer - level .1%

Food Chains and Food Webs

food webs are better than food chains because food webs are just a bunch of food chains put together so a food web is just a better version of a food chain.

Trophic Levels and Energy Pyramids

If you take out the bull kelp than the short pine urchin and the dugong will have to get off a different plant. It will probably start to limit the the plants that the short pine urchin and the dugong are eating off of.

they chose a pyramid instead of any other shape because it gets smaller as it goes up just like the amount of energy they get. They get a smaller amount of energy as they go up the pyramid.

producers are the largest level because they have the most energy and the top is the smallest because they get the smallest amount of energy.


CO2+H2O ----> C6H12O6+O2

photosynthesis NEEDS the suns energy, carbon dioxide, oxygen, water, glucose.

photosynthesis PRODUCES food for the plants and oxygen.

photosynthesis takes place in the chloroplast in a plant cell

seaweed is one of many tropisms in a coral reef.

some examples of tropisms are seaweed and pretty much most plants the are called phototropism

coral reefs depend on fish to eat the seaweeds with which the corals compete, and without such cleaning the reef decline as corals are replaced by seaweed.

The Role of Decomposers

they help keep oceans full of the nutrients that plants did not grow, many coral reefs herbivores would starve

some decomposers are sea cucumbers, snails, and bacteria


So that thy can survive in their own environment.

some fish have to adapt to a different body structure to easily maneuver through coral. some fish even have bright colors to attract mates and camouflage.

some different adaptions are bright colored fish, body changing, and coral with has adapted toxins to keep away predators.

If you put them in a different environment they would probably be confused and would have to find new shelter and places to find food.

Natural Selection

Natural selection is the gradual process by which heritable biological traits become either more or less common in a population.

A type of natural selection is Acanthurus Olivaceus and A Reversus the Olivaceus has a much bigger population than the Reversus.

i recommend being more specific with your abiotic factors

I recommend that you could add more pictures and that you could be more specific on your water and sunlight 😃

I recommend that you should describe the abiotic factors more.

I recommend that you type in complete sentences, but other than that your tackk was great!
