What is Being Done?
What is a habitat and why is it important?
All organisms (living things) have a habitata home or place where they are able to meet their needs for life. Different organisms meet their needs in different ways; therefore habitats are very diverse. A habitat may be big or small, on land, in the ocean, or deep within hot volcanic rock. The diverse habitats on Earth are all interconnected. They do not have clear borders, not even between land and sea. An example of this is an underwater coral reef habitat connected to a mountain top habitat. When a large storm washes sediment off the land and into the ocean, the sediment may blanket the coral reef. Coral may die as a result, affecting the habitats of many organisms that live in and around coral reefs. This is one example of how a habitat can change. Habitat changes can be caused by natural events such as hurricanes or tsunamis, or by human disturbances.
What are some kinds of marine habitats?
Some marine organisms have large and varied habitats:
Marine habitats include the places where ocean-dwelling organisms live and meet their needs. Many marine animals migrate far distances during the year and use a variety of habitats. For example, sea turtles use the open ocean, coastal areas, and beaches during their lifetimes. They may migrate hundreds of miles between their breeding territory and their feeding territory. Some organisms, such as the Black-footed Albatross, move throughout the entire Pacific Ocean. These birds breed in the Hawaiian Islands and in Japan.
Some marine organisms have very specific habitats:
Some marine organisms live in small and specific habitats that meet their needs. For example, phytoplankton only live in the surface layers of the ocean because phytoplankton need access to sunlight. There are marine bacteria that only live in deep ocean vents where they use sulfur from inside the Earth to produce sugar.
