Oceans the King of Biomes
Transcript of Oceans the King of Biomes
The ocean's temperature is constantly changing and is different all around the world Adaptions Co-Op and Competition Oceans of the Earth Found covering earth this is the reason Earth is known as a great blue marble in the galaxy . Ocean biomes are found all over earth. They cover 75% of Earth and can have the most sever weather changes and house the largest animals and most diverse species of an animal. Abiotic Factors Native Animals Coral Narwhal Whale Shark Endangered Animals Dugong Saw Fish Sea Otter 2.Pressure
The ocean pressure
changes as you go
stronger and heavier 3. Light intensity
the light intensity is divided. Sunlit Zone, Twilight Zone, and the Midnight Zone. Native Plants 1. Kelp
Kelp forests grow predominantly on the Pacific Coast, from Alaska and Canada to the waters of Baja California. Kelp favors nutrient-rich, cool waters that range in temperature from 5o to 20o C 2. Algae
Are a very large and diverse group of simple organisms. Algae exhibit a wide range of reproductive strategies, from simple, asexual cell division to complex forms of sexual reproduction. Native Plant Adaptions Salinity Tolerance Buoyancy Adaptations Structural Differences From Land-Based Plants. Two major differences between oceanic plants and land based ones are structural. Land-based plants use roots to pull up nutrients and water from the soil using vascular action, and the entire structure of the plant is built around this function. This explains why plants have stems, for example. On oceanic plants, the root structure is called a keepfast, and is an adaptation meant to anchor the plants against the currents, and there is no need for internal water transportation within the plant. Indeed, most oceanic plants are more properly typed as macroscopic algae than vascular plants. There are many native animals in the ocean big, small, horened, and some who dont even look like animals. Narwhal males are distinguished by a long, straight, helical tusk, actually an elongated upper left canine.Narwhals are medium-sized toothed whales that lives year-round in the Arctic. Corals are marine animals. Coral can be part of the physical structure of the coral reefs that develop in tropical and subtropical waters, like Great Barrier Reef near Queensland, Australia. Coral can be found off the coast of the U.S. Whale Sharks are slow-moving filter feeding shark and the largest still living fish species. The whale shark is found in tropical and warm oceans and lives in the open sea with a lifespan of about 70 years. The species originated approximately 60 million years ago. The species was distinguished in April 1828 In order for narwhals to talk through the deep, icy waters they adapted a high range of echo location which is very high clicks, squeals, and whistles. Whale sharks have no adaptions. Coral has developed reproductive, feeding and social behaviors that allow them to gain the maximum survival benefit from their situation. Coral also uses long toxic tentacles they adapted. Suggested Supplies/Gear 1. Boating-take a relaxing boat ride
2.Snorkeling- go under the waves
3.Scuba Diving-dive to the deep and see the sea. Rec Activities Points of Intrest 94 percent of life on Earth is aquatic. We have only explored less than 5 percent of the Earth’s oceans. In fact, we have better maps of Mars than we do of the ocean floor (even the submerged half of the United States). Nearby Biomes Any Biome can be near or adjacent to the ocean, Like the temperate forest of North America or the Tundra of Antarctica. Average Precipitation Tropical areas, such as the Inter-tropical Convergence Zone, where northern and southern trade winds bring evaporated water vapor, can get 115 inches of rain each year while most of the oceans receive 29 inches per year Average Temperature The average temperature of all oceans is about 39 degrees F (3.8 degrees C). If you are going into the ocean you would want to wear a swim suit, or if are going to be around it, you would want to wear shorts and a shirt or anything you wouldn’t mind getting wet Threats to the Ocean Threats to Marine biomes include overfishing, that can endanger certain species or even drive them to extinction. Oil is also a threat as the toxic of the oil kills and harms native animals. Ocean bottom habitats degraded by dredging and trawler fishing; over harvesting There are many endangered species such as blue whales, otters, coral, saw fish, and dugong. The whole saw fish family is largely unknown and little is studied of them. They are not to be confused with saw sharks which have a similar appearance. The sea otter is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Although it can walk on land, the sea otter lives mostly in the ocean. The dugong is a large marine mammal and together with the manatees, is one of four living species of the order Sirenia. The dugong is the only strictly marine herbivorous mammal. The dugong has been hunted for thousands of years for its meat and oil. Impact of Climate Change Warmer waters causes coral bleaching. Which negatively impacts the entire coral ecosystem. Many species will have to migrate to maintain temp conditions they need to survive. People and industries rely on the ocean and other natural resources for food, or tourism. If warming or freezing waters affect life in the ocean, it will affect us too. Alteration to water temperature can directly impact development, age of sexual maturity, timing of spawning, growth, and survival of most fish and cephalopods. The Importance of Oceans Throughout history humans have been directly or indirectly influenced by the ocean. Ocean water serves as a source of food and valuable minerals, as a big highway for commerce, and give a place for both recreation and waste disposal. It has been assumed that about 10% of human protein comes from the oceans. The oceans also are important for R.E.C use, as each year more people are attracted to the sports of swimming, fishing, scuba diving, boating, and water skiing.
