The importance of coral reefs in marine ecosystems is virtually immeasurable. Coral reefs support more species per unit area than any other marine environment, including about 4,000 species of fish, 800 species of hard corals and hundreds of other species.  It also gives those marine animals a place to hunt. Marine ecosystems are very important in to the overall health of both marine and terrestrial. Commercial fishing, loss of nesting habitat and climate change are among the human-caused threats pushing sea turtles towards extinction. The ocean contains more than 97% of the world’s water. The ocean ecosystem covers most of the earth's surface and is home to millions of plants and animals. The Marine Ecosystem is the Largest Ecosystem on Earth.

Home to exceptional biodiversity In these labyrinths of living limestone, scientists estimate that more than a million animal and plant species are associated with them and that they are home to more than 25% of all marine life. It provides food in the form of fish and shellfish—about 200 billion pounds are caught each year. integral part of their ecosystem by performing specific functions that are often essential to their ecosystems and often to human survival as well What is an ecosystem? These plants absorb carbon dioxide and turn it into oxygen through photosynthesis. ... these microalgae provide two important services. One of the most important functions of marine ecosystems is the production of plant biomass from sunlight and nutrients (primary productivity), which represents the basic food source for all life in the ocean, and ultimately also for humans. Aquatic plants absorb carbon dioxide from the air, and it releases oxygen back in the atmosphere.  Marine ecosystems are considered to be the habitats that complete the larges system from the shores to the dark sea floor. Marine ecosystem models are valuable tools for understanding marine ecosystem function, structure and productivity under global change. Overfishing is a threat for marine ecosystems because a decrease in number of a species will effect the marine food web disrupting the whole ocean. Are causing problems for the marine life. Marine ecosystem models have grown increasingly complex over the past decade in response to the growing appreciation of the complexity of marine ecosystems, and also to satisfy the need for flexible models that can be used for global biogeochemical simulations and for coastal and estuarine management applications. Damaged or imbalanced ecosystems can cause many problems. Marine ecosystem services support our daily lives in a number of ways. Marine biodiversity has a numerous variety of species and organism. Ocean Resources The ocean is one of Earth 's most valuable natural resources. As apex predators, sharks play an important role in the ecosystem by maintaining the species below them in the food chain and serving as an indicator for ocean health. attention to the importance of marine microorganisms for the production of oxygen (approximately 50% of the total photosynthesis on Earth), the removal of carbon dioxide from the atmosphere and the regulation of our climate. It includes microbes, plants, fishes, animals, insects, reptiles, mollusks, etc. See more ideas about art for kids, ocean diorama, crafts for kids. Marine ecosystems make up the largest aquatic system in the world covering more then 70 percent of the planet.

They have great biological diversit…  Without all the marine ecosystems, the marine food web and the whole ocean would be in danger of continuing in its current state. Abelson: Marine ecosystem restoration (MER) is a developing field of applied science and is rapidly growing in importance as marine ecosystem degradation accelerates. The topmost part of a marine ecosystem is the euphotic zone, extending down as far as 200 meters (656 feet) below the surface. The average ocean depth is about 12,000 feet and the deepest point is the Mariana Trench in the Pacific Ocean with a depth of about 32,800 feet. group of organisms living together in a specific environment Components. 0000001977 00000 n In this system, multiple food webs i.e. The oceans alone cover about 70% of the Earthâs surface or 140,000,000 square miles.

Studying ecosystems is known as ecology. 0000002531 00000 n Thus, a more accurate name for Earth would be The aquatic equivalents of biomes are called aquatic life zones. Ecological importance of sea turtles in coastal marine ecosystems Sea turtles have experienced dramatic declines over the past century. Marine microbe communities can evolve rapidly in response to environmental shifts and could be used as indicators of ocean change.
