Ocean ecosystem #ecosys6


here are some biotic things in the ocean!

coral is considered a biotic factor.


Great White Shark


hey is that nemo?🌊


in the ocean the sand on the bottom is abiotic and here are so more examples!

The water temperature (ranges from 38 degrees C- 0 degrees C)

The dry or moist sand








carrying capacity- life that is supported by resources in the eycosystem.

for example if fishermen caught almost all the male fish in the sea then the female fish wouldn't be able to reproduce. Since they couldn't reproduce the population goes down as the die off. That also makes the population of the sharks go down because even though they eat more than fish, the fish population has decreased by huge numbers so the Sharks have one more less resource, but the eggs that were laid could be a boy or girl the boys born would be able to help reproduce to make the numbers go up again.


Limiting factors- a factor in your ecosystem that makes a huge change.For example light, temperature, gases, saltiness, etc...

Energy Roles

producers: Seagrass, Mangroves, Plankton

consumers: Great white sharks, Clown fish, Surgeon fish, White tipped dolphins, Zebrafish

decomposers: Bacteria, Fungi, Pistol shrimp,

This is a mangrove, which is a producer. This mangrove gets its energy from the salt in the oceans water.

This is a great white shark, which is a consumer. In this picture the great white is getting his energy from a fur seal, but receives energy from many other sources.

This is a Pistol shrimp, which is a decomposer. it gets its energy from eating macroagle that lives right outside their burrow entrance.

The role of producers in the energy transfer is to take the radiant energy and change it into glucose and the waste comes out as oxygen. Almost every living thing in the earth needs oxygen so that's the role of producers, to release oxygen.

food chains and webs

for my ecosystem a food web would be a better selection than a food chain because the food web goes way more in depth and shows more of producers, consumers, and decomposers than a food chain would.

if I were to remove one population from my food web then most of it would fall apart because without one part of the web it is pretty much worthless. expecially if you take out the sun or the shrimp like creatures the whole thing would fall apart.

the shape of this energy pyramid is perfect for its purpose because is shows the levels that gives the most energy to the level that gives off the less energy and it shows that by the size/level the organism is in.

the producers are the bottom and the biggest level of them all because it gives and receives the most energy direct and indirectly. the top producers are at the top and the smallest level because there are very few things that don't get eaten by anything but decomposers when they die.


c6h12o2 is the chemical formula.

for the process of photosynthesis the need reactants are water, carbon dioxide , and sun light. Oxygen is produced as a waste product and glucose(sugar) is also produced.

the energy transformation taking place in photosynthesis id radiant to chemical. The sunlight taken in by the plant is transformed into glucose making it a chemical change.


Tropism is the movement or bending of the organism away from an external stimulus such as light or heat.

examples: seaweed ,kelp, seagrass

In my ecosystem these organisms help keep other organisms survive because they are producers and give off energy and oxygen to the living organisms in the ocean.

The role of decomposers

The role of decomposers id very vital to the ecosystem because they swim to the bottom and decompose of all the dead organisms, which gives them nutrients that they then carry back to the living organisms. If there were no decomposers there wouldn't be as much nutrients and the soil wouldnt be as healthy so the plants couldn't produce as much as need for the environment.

examples: snails, shrimp, starfish, crabs, and seaweed.


The purpose of all the adaptations in the ecosystem is so the organisms can survive in their ecosystem. the two different types of adaptations are physical and behavioral. Physical adaptation is the way a plant looks or is shaped and behavioral is the way an organism acts. These adaptations help organisms adapt to their enviromebt so they can survive.

I recommend that you put more biotic and abiotic factors

👍 I still have a question about how coral is abiotic and biotic. Isn't coral considered living?

i recommend that you add more aboitic things so that they even out

You need to capitalize producers consumers and decomposers

I recommend adding your graphics, such as the pyramid, in a button, when you finish with the graphic
