The Aquatic Ecosystem

The Biotic Factors of this ecosystem are:
Animals                                     Plants
-Fish                                        -Corral
-Shark                                     -Seaweed

The Abiotic Factors of this ecosystem are:
-Water Depth

Carrying Capacity- The largest number of individuals of one species that an environment can support

The resources a population needs to survive are:





The population does not go on forever because if a predator's population goes down, the prey's population goes up. If the prey's population goes down then the predators population goes up.

Limiting Factors- Any factor or condition that limits the growth of a population in an ecosystem

Examples of Limiting Factors are:




-Depth of water


The competition in the ocean between predators and prey involves the population. Does the population stay the same forever? No. When predators eat their prey, the prey's population goes down while the predator gets to survive longer. Does a predator's population stay the same forever? NO. They can be eaten by other animals too. Prey population goes up once their predator's population goes down.

Energy Roles- determines how organisms gain energy and interacts with other organisms in an ecosystems

Consumers are one of the energy roles because they gain energy by not making their own food and eating other animals.
Great White Sharks are an example of being a consumer because they obviously don't make their own food.

Producers are part of the energy roles because plants don't eat other animals... they make their own food by doing a thing I would like to call... PHOTOSYNTHESIS!
They get their energy by the sun:)
Seaweed is an example of a producer because they make their own food.

Decomposers are part of the energy roles by getting energy from dead organisms and releasing nutrients in to the ecosystem.
Bacteria is an example of a decomposer because it releases the nutrients into the ecosystem.

Food Webs are more realistic than Food Chains because Food Webs have more predator/prey relationships all at once.

If I were to take the Crab population out of the ecosystem, the Shark, PufferFish, Squid, and Killer Whale population would decrease and they wouldn't survive for very long.

In the Energy Pyramid, each Trophic Level gets about 10% of energy. About 90% of the energy is used up from life processes or heat loss. The Producers is at the bottom of the pyramid because it is the Trophic Level that gives the most energy. Producers get their energy from the sun which is Chemical Energy.

This is the Photosynthesis cycle of Algae.

The Chemical Formula of Photosynthesis are:

What is needed for Photosynthesis are:
-Carbon Dioxide

What's produced by Photosynthesis is Carbon Dioxide and Water

Tropisms- the turning or bending movement of a plant that grows towards or away from/to the stimulus.

Green Algae is an example of a tropism because it is a type of plant in the ocean. It contains two forms of Chlorophyll which they use to capture light in order for the plant to make its own food.

Another Example of a tropism is Kelp. Kelp is a type of plant in the ocean that contains a large amount of seaweed and supports a large population of animals.

Decomposers are Vital to the ocean ecosystem because they are considered as "Cleaners" to the ecosystem. They thrive to decompose the organic wastes of dead animals and plants, both in water and on land. The affect of having no decomposers would be that there would not be any more nutrients in the ecosystem, which would leave out carbon, nitrogen, and phosphorus.

Types of Decomposers in the Ocean.

Ocean Algae could be found in the ocean ecosystem because they break down nutrients to release carbon,nitrogen, and phosphorus.

This is the Decomposer Graphic.

The importance of having Adaptations in an ecosystem is to inherit traits to become more structural and behavioral and to be best suited for its ecosystem.

Plant Adaptations:
-Broad leaves can capture a lot of sunlight for a tree
-Some plants produce seeds that can float

Animal Adaptations:
-Great White Sharks can not see very well because of the countershading, which reduces the contrast between its belly in the shark's bulk, and its back illuminated into the sunlight
-Fish eat their prey by eating under their snout/longer upper jaw

The affect of placing an organism in a different environment is that they will not have shelter, space, food, and water. Organisms need to be in a specific environment because of that reason. As a result, they will not be able to reproduce which makes them extinct, then, obviously, they will not be able to survive for a longer period of time.

Natural Selection- inheritable traits that become more/less common in a population. It is important because It is the one process that is responsible for the adaptations of organisms in their environment.

How Natural Selection changed Great White Sharks is by surviving extremely violent events and slower genetic processes in Natural Selection.
