Biotic Factors:

Fish, Sharks, Clams, Whales, Sea Cucumbers, Coral, Sea Weed, Sea Horses, Seagull, Jellyfish

Abiotic Factors:

Abiotic: Water Temperature, Water Currents, Tides, Rocks, Sand

Carrying Capacity:

Populations Of Certain Animals/Prey May Affect The Population Of The Predator That Eats The Prey.

Energy Roles
Food Chains And Food Webs

Food webs are more realistic for my ecosystem than food chains, because there are way more animals and organisms. A food web shows more because you can have multiple producers, consumers, etc. Where as with a food chain you can only have one of each.

If I removed an organism from the food web it would ultimately cause the population of the organism that eats it to die out.

Producer: Makes Their Own Food, have to most energy (on the bottom of the food chain)

Herbivore: Eats Plants

Omnivore: Eats Plants And Meat

Trophic Levels & Energy Pyramids.

Some limiting factors of the ocean are: temperature, sunlight, pressure, oxygen concentration and nutrient availability.


CO2+H20 - C6H12O12

Water, Oxygen, Carbon Dioxide, and radiant energy are needed                            glucose is made


Movement away from an external stimulus, such as light, heat, or gravity.

If algae could not attach itself to rocks or other objects it would eventually have no where to survive and die off.


If the ocean had no decomposers it would be filled with dead plants and animals which would pollute the ocean causing other ocean creatures to die.

In the ocean, fungi break down dead seaweed and release phosphorus, nitrogen and potassium back into the ocean. The majority of decomposition occurs on the floor of the ocean because organisms tend to sink after they die.

Shrimp: Crustaceans are especially well-suited to life as scavengers. Crabs, lobsters and some species of shrimp live primarily or exclusively on the remains of dead animals.


Adaptations are important because if organisms in their environment didn't know how to find food, water and other things they needed to survive they would all eventually die.

An example is how Sea Horses are able to wrap their tail around Coral and other things so they wont float away.

Natural Selection

Natural selection is the process by which the organisms in a population that are best adapted to the environment increase in frequency relative to less well adapted forms, over several generations. The consequence of natural selection is that through time species develop characteristics that make them increasingly well-adapted to their environments.

Sharks are an example of this, having a color pattern that makes them blend in. When you look at a shark from above, its dark blue or gray topside will blend in with the background of the deep and dark blue sea. When you look at a shark from below, its white belly will blend in with the bright colored surface waters along with the sun.

This coloration evolved due to the sharks blending in with these two different backgrounds. The theory is that sharks blending in with the dark blues of the deep sea are difficult to spot from above and therefore their prey would not see them coming, and as a result those sharks would feed more often due to a higher rate of successful hunting. The same goes for blending in with the bright surface waters from the bottom of the ocean.
