Ocean Habitats
An Ocean Habitat or sometimes refer to as a marine environment is a place in the ocean where plants and animals interact with the chemical and physical features of the environment. An Ocean habitat is a place where communities of organisms live. The three main ocean habitats of the ocean are the open water, the soft sandy to muddy bottom and the hard shore. Examples of ocean habitats are the coral reefs, the estuaries and the abyssal zone. Habitats can be classified in a number of ways in order to compare them at different times, across different geographic areas, and in terms of different life history strategies. Habitats are as varied as the animals that live in them and each could be infinitely described, but another general way to think of them is according to their measurable characteristics, or parameters. Examples of habitat characteristics include temperature, moisture, substrate type, nutrient availability, altitude or depth in water, and amount of light and wind or current in water. Coral reefs are the most diverse and beautiful of all marine habitats. Large wave resistant structures have accumulated from the slow growth of corals. The development of these structures is aided by algae that are symbiotic with reef-building corals, known as zooxanthellae. Coralline algae, sponges, and other organisms, combined with a number of cementation processes also contribute to reef growth. A coral reef is made of thin layers of calcium carbonate A coral reef is very effective at absorbing nutrients from the waters surrounding it. This includes obtaining phosphorus and nitrogen from sea waters, and other nutrients from small organisms making their home in the coral reef. A coral reef is one of the largest living communities in the world. Thousands of species make their home there, including over 4,000 different tropical fishes, jellyfish, crabs, sea urchins, and starfish. Mammals may visit a coral reef, but none actually live on or near

    Marine habitats are in grave danger due to humans and Mother Nature. Hurricanes, typhoons, storm surges, and tsunamis are factors in which contributes to the destruction of marine habitats and are caused by Mother Nature. Human’s destruction to these habitats is much worse due to the fact that Mother Nature’s destruction is mostly temporary, while humans leave more of a lasting footprint on the habitats because of our persistence.

Marine habitat destruction caused by humans are wetlands being filled for further development, runoff water which carries chemicals, pollutants, and wastes are pumped back into the water without…

    The ecosystem of the reef is fairly straight forward. The main energy source for the producers of the reef (Algae, Kelp, and Plankton) is sunlight and water which provide them with nutrients. The producers provide resourceful energy for organisms (Warreners, Elephant Snail, and Sea Urchin), in order for them to survive. These organisms are eaten by the marine carnivore organisms (Common Sea Star, Dog Winkle) for sufficient energy. Birds and Fish gain their energy by obtaining most of these heterotrophs and autotrophs. The characteristics of the ecosystem play a big part in order for the ecosystem to survive.…

    Coral reefs are communities to the sea and home to many living creatures and different types of organisms, as well as about one-fourth of the oceans population. Coral reefs are made up of animals called polyps that will remain in one place, acting as the main structure of the reef itself, these animals have a hard almost skeleton like structure. Scientists who study coral reefs have categorized them into three different types of reefs; Barrier reefs, Atolls, and Fringing reefs. Coral reefs are put into these categories based on their size, shaped and close proximity to land. Although corals are grouped together, "An individual coral is known as a polyp, a very small and simple organism consisting mostly of a stomach topped by a tentacle-bearing…

    Coral reefs have been dubbed the “rainforests of the oceans”, because of the rich diversity of life they support, as more than one quarter of all marine animals depend upon coral reefs. Coral reefs are also a source of food and income for millions of people. The coral reef ecosystems benefit humans commercially, recreationally and environmentally. Without them many tourism based industries would collapse, treatments or cures for some illnesses would disappear, and the countless organisms they support would be left without food or shelter. For these reasons and numerous others, it is vital that we protect coral reefs.…

    Within each ecosystem, there are habitats which may also vary in size. A habitat is the place where a population lives. A population is a group of living organisms of the same kind living in the same place at the same time. All of the populations interact and form a community. The community of living things interacts with the non-living world around it to form the ecosystem. The habitat must supply the needs of organisms, such as food, water, temperature, oxygen, and minerals. If the population's needs are not met, it will move to a better habitat.…
