The population of Sharks, for example, could differ because if certain fish,seal,etc started dying out or something and the sharks would have no food supply so the population would start to decrease.
Factors that limit the type of life forms able to live in an ocean environment include temperature, sunlight, pressure, oxygen concentration and nutrient availability. Because of its many varied attributes, the ocean offers a unique home to aquatic life.
Some limiting factors of the ocean are:

Producers: In the ocean, there are no "green plants" to make food. Seaweeds such as kelp are one of the oceans producers. The main producer in the ocean is Plankton.
Each of the energy roles receive its energy from:
Plankton, like most organisms gets it's energy from sunlight.
Producers are vital to any ecosystem because they basically start the whole food chain/web...without them other organisms wouldn't be able to have any food..meaning if ecosystems didn't have producers there would technically be no ecosystem, because the other organisms wouldn't have any food, so they wouldn't be able to survive.
FOOD CHAINS & WEBS
Food webs are more realistic for my ecosystem than food chains, because there are so many different organisms, producers,consumers, etc. A food web would show many of the different types of organisms in the ocean, while the food chain would only show 4-5.
If I were to remove an organism from the food web it would effect the population, because (say I removed a secondary consumer) the other consumers wouldn't have a food source an eventually die out.
TROPHIC LEVELS & ENERGY PYRAMIDS
The energy is a pyramid, because is helps represent the lower levels, and higher levels, by sectioning off the whole shape.
Producers are in the largest level, because they have the biggest role in ecosystems, they are basically the vessel or base for an ecosystem, because without producers there would be no other organisms.
CO2+H20 -------> C6H12O12
What is needed: Water, Oxygen, Carbon Dioxide, Glucose
What is produced: Radiant Energy
Where photosynthesis takes place in plant cells: In chloroplasts inside the plant cell.
A Tropism is a growth or turn of a plant in response to a environmental stimulus.
An example of a tropism in the ocean would be if there was a plant growing on the side of a rock, and it turned and grew upwards towards the sun, that would be a phototropism, because the organism is turning towards the sun.
This tropism helps organisms in this ecosystem survive, because the sun provides energy the plant needs to survive.
Decomposers are the biotic or the living factors that occupy the fourth place in an ecological food chain. Decomposers are considered as ‘Cleaners’ of the ecosystem as they thrive to decompose the organic wastes of dead plants and animals, both in water and on land. Since oceans cover 70 % of the earth’s surface (most of water being salt water) , we find a large and extensive variety of oceans animals and plants. The marine biome is made up of salt water regions and includes estuaries, coral reefs, shores, and the open ocean. The ocean biome is therefore the biggest biome compared to the terrestrial or land biome and the total number of organisms in the ocean is bigger than all organisms of land biome. This in turn serves to increase the number of decomposers in the ocean biome.
ROLE OF DECOMPOSERS
Adaptations help organisms survive, because without them organisms wouldn't be able to do the things they do, for example, sharks have adapted sharp teeth so they can chew the fish. If they didn't have sharp teeth they wouldn't be able to eat... (it would be pretty hard to eat fish with just gums)
I think an if an organism was moved to a different environment other than the one its adapted to it wouldn't survive, for example a fish, if you were to move a fish to a rain forest, there is no way it would survive, because it's meant for the water, they have fins so they can move and gils so they can breathe underwater, they arent meant to breathe above water, so they would eventually sufficate and die.
Natural selection is the gradual process by which heritable biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. It is a key mechanism of evolution.
An example of natural selection in the ocean is camouflage sea horses.
If a predator is searching for prey then it makes sense that the animals that are easiest to see will be spotted and eaten first, correct? This means that the animals that are hardest to see will have a better chance of surviving and reproducing. These hard to see animals will pass their genes on to the next generation while the easy to see animals won't pass their genes on to the next generation because they were eaten!
