Marine Biome (Coral Reef )Shakira Kurniawan

Characteristics

Biotic Factors ( Animals ):Octopus: In the great barrier reef, blue octopus are endangered animals. It’s camouflage by flatten its body, hide and changes its colour.

Sharks: I’ve chosen the white tip reef shark. The hunting behavior of the shark is to hunt at night while the other fishes are sleeping.

Dolphins: Dolphins are mammals. One section in its brain, it can hold all senses.

Blue ringed Octopus

Characteristics

Biotic Factors ( Plants ): Coralline algae: Coralline algae are red algae. They grow from the surface to the depths of more than 100 meters.Seaweed: Seaweed can only adapt to salt water. Seaweed doesn’t have a root system. It grows on top of rocks to absorb sunlight, which is call photosynthesis.

Characteristics Abiotic Factors:

Water pressure: At sea level, the air that surrounds us presses down on our bodies. We don’t feel it because the fluids in your body are pushing outward with the same force.Tides: Tides affect marine life by creating different niches where certain organism can live. Carbon Dioxide: When carbon dioxide absorbs in seawater it creates carbonic acid, which lowers the pH level of the water. This is called ocean acidification. On top of the ocean acidification, global warming from increased atmospheric carbon levels is also warming the oceans.

Producers Adaptations

Coralline algae: Coralline algae are plants that can’t live in different types of water. They also need rocks to survive and grow. Red algae is unique because it has adapted to be able to do photosynthesis not only in light,but also in the darkness at night. It means that coralline algae can still thrive in low light, as long as the water has enough oxygen.

Phytoplankton: Phytoplankton are very tiny organisms. The phytoplankton doesn’t even need roots to survive like other plants, because they can absorb water and nutrients directly from their environment.

Animal Adaptation

Dolphins have adapted to its environment. Such as its shape of its tail. A dolphin’s tail go up and down to help it dive up to get an air. The shape of their fins also helps to propel in water. To help dolphins save oxygen while they dive underwater. Their heart beats slows during a dive and their blood is diverted from other parts of their body to their heart, lungs and brain. Dolphins also save oxygen via their muscle which have a protein called myoglobin which it stores oxygen. Dolphins also have blubber or fat, which provides insulation to keep the dolphin warm in cold water.

Animal Adaptation

The white tip reef shark has remarkably sharp teeth. Its best for them because they are carnivores and they can chew easily. The white tip reef shark is a nocturnal creature. Its eyes are large and oval, which help the shark see well in the dim light. It also uses its strong chemosensory and electroreceptor system to help it locate its prey in the dark.

Animal Adaptation

The blue ringed octopus has sharp beaks for biting. They are very fast and could shoot venom into the water, but they don’t really have that much ink. They are about the size of a golf ball. So, they could easily hide. They also have the capability camouflage. Its camouflage capability is to hide in every places because its small! When the octopus is harmed, those blue rings will come out. That stands for defense. It could be gray or beige when no one is attacking it.

Conservation Issue There is a few of conservation issue in the marine ecosystem. Human

caused a lot of problems to affect the ecosystem. They did discarded trash, oil spills, sewage spills and toxic chemical runoff which negatively impact the marine life. Sewage is water carried waste, in either a solution or suspension form and intend to flow away from a community. The waste could be washing water , food preparation wastes and laundry waste. Sewage spills are serious problems that may lead to serious health risks and environmental damage. I think it might damage the living organisms there, and they could die. I also think that the abiotic factors such as the water might affect it. I think we could help by cleaning up, conserving energy and chiming in.

This is a picture of a sewage spill.

Did you learned a lot about the marine ecosystem?
