Types of water bodies marine water
- 1. MARINE BIOME DR. SURJYA KUMAR SAIKIA DEPARTMENT OF ZOOLOGY VISVA-BHARATI
- 2. Objectives 1)To provide a description of marine aquatic biome. 2)To know different principle characteristics, types and nature of the marine ecosystems
- 5. BASICALLY, WE HAVE 2 MAIN TYPES OF AQUATIC BIOMES 1. Marine water 2. Fresh water
- 6. The marine biome is an environment characterized by the presence of salt water. It is found in all of Earth's oceans and is the largest biome in the world
- 8. MARINE ECOSYSTEMS OPEN MARINE ECOSYSTEM1 OCEAN FLOOR ECOSYSTEM2 CORAL REEF ECOSYSTEM3 ESTUARY ECOSYSTEM4 SALWATER WASTELAND ECOSYSTEM5 MANGROOVE ECOSYSTEM6 All images from pixhere.com
- 9. Marine open ecosystem Major type of marine ecosystem Sea life that float or swim The euphotic zone and extends to a depth of about 150 meters Freeimageslive.co.uk Commons.wikimedia.org Aims.gov.au
- 10. Ocean Floor Ecosystems Shallow water, sunlight can penetrate to the bottom Certain types of fish, crustaceans, clams, oysters, worms, urchins, seaweed and smaller organisms At greater depths where sunlight cannot penetrate, organisms can generate their own light Commons.wikimedia.org Pixino.com Pickpik.com
- 11. Coral Reef Ecosystems Subtype of seafloor ecosystem Found only in warm tropical waters and at relatively shallow depths About one-quarter of marine species depend on coral reefs for food, shelter or both Pikrepo.com Pixino.com Commons.wikimedia.org
- 12. Estuary Ecosystems Shallow, sheltered area of a river mouth where freshwater intermingles with saltwater as it enters the sea The organisms inhabiting estuaries are specially adapted to these distinct conditions; hence, the diversity of species tends to be lower than in the open ocean Serve an important function as nurseries for many types of fish and shrimp Wikimediacommons.org
- 13. Saltwater Wetland Estuary Ecosystems A special type of estuary, as they also consist of a transition zone between land and sea The organisms inhabiting estuaries are specially adapted to these distinct conditions; hence, the diversity of species tends to be lower than in the open ocean Serve an important function as nurseries for many types of fish and shrimp imaggeo.egu.eu Saltwater swamps Salt marshes Wikimedia.org Saltwater swamps Salt marshes
- 14. Mangrove Ecosystems Special types of saltwater swamps Characterized by trees that tolerate a saline environment, whose roots systems extend above the water line to obtain oxygen, presenting a mazelike web Host a wide diversity of life, including sponges, shrimp, crabs, jellyfish, fish, birds and even crocodiles Flickr.com Pixabay.com

- 17. 1.Pelagic zone • -includes those waters further from the land, basically the openocean www.pinterest.nz This slide is used only for academic purpose
- 18. Facebook.com 3. Benthic zone - isthe area below the pelagic zone,but does not include the very deepest parts of theocean
- 19. www.elephango.com Abyssal zone 4 -Thewater inthis region isvery cold (around 3°C),highly pressured, high in oxygen content, but lowin nutritional -deep ocean
- 20. What we have learnt….. Marine Biome is actually a salt water system. There different zones in marine ecosystems A large biodiversity in Marine biome exist in photic zone There are six major types of Marine Ecosystems, namely, (i) Marine Open Ecosystem, (ii) Ocean Floor Ecosystem, (iii) Coral Reef Ecosystem, (iv) Estuary Ecosystems, (v) Saltwater Wetland Estuary Ecosystems and (vi) Mangrove Ecosystem
