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. [1] 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.
