The Ocean

Biotic factors in the  ecosystem

Coral reefs







The Abiotic factors in this ecosystem are:

Salt water




Carrying Capacity and Changes in Populations

   For this population to survive, They would need their providing producer: Plankton, Alge, ect., And their primary consumers: Small fish, Clams, ect. Secondary consumers: Crabs, Orkas, ect. and the last but not least the Teritary consumers:

   For example, say the shark population increased by 50% and the seal population decreased by 70%, both populations would be affected by the shark loosing its over population and the seals could, if they don't reproduce in time, could die out. On the other hand, the seal population could increase by the dying of the sharks and cause this situation to happen again.

Limited Factors

                                         Limited factors in the Ocean:

1. Dying of prey.

Some bigger animals may eat more, or if another cause, could loose a lot of their prey, and that could cause a die out of them.

2. Pollution.

With the trash and oil being put into the water, some animals could soon die and become extinct because of this.

Energy Roles

1. Producers

Producers: Kelp/ usally eaten by the herbivors/ Primary consumers.

2. First level

Primary consumers: Small fish, and some smaller organisims.

3. Second level

Second level consumers: These animals are from dolphins to otters. Soms are omnivores and others are just carnivors that have a bigger foe. The suprisingly the dolphin can be in both the second level and the third. also jellyfish are in this category aswell. This category can get its energy from the primary consumers or/and the producers.

4. Third level

Third level: Sharks, Dolphins,and Otago. Humans are the top in this foodweb! These consumers can either eat from this catogory to the primary consumers. rarely do you have a shark eating kelp or phytoplankton.


the plants here dont get much sunlight, so phytoplankton help feed the smaller organisims and then they feed the small fish and then the food chain continues.

Without these small producers, the primary consumers would have nothing to eat and the foodweb would topple down.

Foodwebs vs Foodchains

Foodwebs, show if an organisim is an omnivore or a herbivor, it shows more foodwebs and facts about an animal.

If you wondered where a whale shark stood in the mess of this, just look at a foodweb to see its predators and its prey.

If you removed a producer, you might get a result of the primary population decreasing. depending on the vegitation and the amout of predators and the producers ability to repopulate quickly.

Trophic Levels and Energy Pyramids

Producers: Phytoplankton, Seaweed.

1st level herbivors/carnivors: zooplankton, cockles, juvenile,stages of fish,jellyfish as well as small fish, crustations, and seastars.

2nd level: larger fish, ect.

3rd level: Squid, ect.

Top carnivors:Sharks, Dolphins,Albatross.

The pyramid gets smaller at the top, or bottom however you have it, and that showes the energy disappearing.

Only about 10% of the energy animals have goes to its next transition. so the energy gets lower and lower as it goes to one organisim to the other.

Producers dont eat other organisims. so they have to most energy and give the most. Predators that are at the top have the least energy because the energy has gon through and is being used up in the animal.


C6,H12,O6 is the formula.

For the cycle to begin, you will have to have H2O, Sunlight, and CO2.


There are several different examples of tropisms in plants. Gravitropism, or the response to gravity, causes roots to move towards gravity, or down into the soil, to reach water and minerals. It also causes stems to move away from gravity, so that leaves and stems will be in a position to intercept light.

Phototropism is the response in plants to unidirectional light coming from one source, such as a lamp or beam of sunlight. Cells on the shaded side of the stem elongate more than the cells on the lit side, causing the stem to turn toward the light.

The Role of Decomposers

Without decomposers, and or scavengers, we would have dead bodies everywhere or slowly decaying. they also give the producers their energy so they can give the consumers their energy.

Bacteria and fungi play an important role in freeing the last of the minerals and nutrients from organics and recycling them back into the food web.Hagfish, worms and other crap that floats in the sea are the decomposers of the ocean biome. Shrimp are decomposers too because like crabs.- Website called


    How the Animals survive in the ocean-

Gils- Gils are important because you cant breath in air underwater, so gils transform the water into the thing the fish and organisms need to "breathe."

Either the fish or the other animals would have to grow legs and lungs to survive the land elements.

Natural Selection

The natural selection in this habitat is mainly for the best looking colours, the protection they have, and the best home for the reproduction.

The clownfish is a great example of the natural selection. The males with the best Home will a quire the best female. The environment changed by having more predators so they got used to the bigger homes and to protect.

Finish up step 5-7, and change limited to limiting factors, but other than that great Tackk
