The Marine Biome By Alyssa Hope Geographical Location • It is the largest of all the biomes covering • • three fourths of the earth's surface. Includes all bodies of water that are salty, such as oceans. There are 7 major oceans in the marine biome and smaller bodies known as gulfs and bays. Rainfall in the Marine Biome • More than half of the rain that falls on the planet earth, fall over the marine biome. • The average annual rainfall for the Atlantic ocean is 1034 mm. Compared to the Pacific, the Atlantic is much drier and has less extreme values. Temperature • The average temperature for all Marine • Biomes is about 39°F (4°C). The sun warms the surface of the water and deep down it is cold. Physical Features - Landscape • There are many mountians and valcanos under • • the water. It just blue open water with lands to boarder around it . There are colorful coal reefs and different kinds of creatures. Physical Features Animals • Mollusks, fish, whales, crustaceans, bacteria, fungi, sea anemones. • Home to the blue whale – the biggest animal on earth. • Most marine mammals have blubber to survive in the cold water. Animals Plants • Marine plants live in the euphotic zone of the ocean • • • because they need energy from the sun for photosynthesis. Over 1 million species of plants and animals have been discovered in the oceans, and scientists say there may be as many as 9 million species we haven't found yet. Algae -One type of marine algae is kelp. It provides shelter and food for a lot of sea creatures. Phytoplankton-tiny plants that serve as food for many of the ocean creatures from the smallest of fish to large whales. Plants Food Chain • Phytoplankton is the first level of our food • • chain, followed by the zooplankton, which feeds on the phytoplankton. Zooplankton are eaten by krill, fish which all go on to be eaten by big fish, penguins, seals, walruses and whales. Without phytoplankton, all of the oceans animals would die. All animals in the ocean depend on plankton for survival. Food Chain Water Cycle of Marine Biome • The water is evaporated from the ocean and then is turned into water vapor and then percipitation. It then rains on the other biomes and eventually ends up back in the oceans. At this point the whole process starts again. The marine biome is important to the earth cause it provides it with 70% of its water. Interesting Facts • The sea otter has close to 1,000,000 hairs per square • • • • inch . Most humans have 10 times LESS on their head. Kelp and Phytoplankton make about 50% of our oxygen. 20 people could stand on the Blue Whale's tongue. There is one cup of salt per gallon of water. The deepest point on earth is the Mariana Trench it is 36,200 feet deep. This is deeper than the tallest mountain.
