open ocean food chain

Ocean Food Chain. Now let's look at an example to see how this ocean food chain works. This order keeps the ocean teeming with life. Lesson 1 - Understanding Food Chains and Webs (2) Lesson 2 - An Ocean of Energy (2) Lesson 3 - Seafood and Human Health (1) Lesson 4 - Sustaining Our Ocean Resources (3) Unit 6 - Life in the Open Ocean (24) Overview - Life in the Open Ocean (1) Lesson 1 - Where in the World is the Open Ocean? The marine food chain is divided into the four categories outlined below. Print. While the ocean seems vast and unending, it is, in fact, finite; as the climate continues to change, we are learning more about those limits. The organisms can be seen as composing a food chain; the three types of organisms: producers, consumers, and decomposers, exist together and feed off each other according to a certain order. Sources Day, Trevor. It is located in the north-most part of the globe. Made of interconnected food chains, food webs help us understand how changes to ecosystems β€” say, removing a top predator or adding nutrients β€” affect many different species, both directly and indirectly. A food chain in the ocean begins with tiny one-celled organisms called diatoms, which make their own food from sunlight. The surface is frozen over with large chunks of sea ice year round. Killer whales are apex predators, which means they have no natural predators. Of course, the menu in the ocean is a lot larger than what your food chain shows! The food chain begins with the tiniest microorganisms who are the major producers of food in the ocean and are in turn, consumed by bigger lives, which are eventually preyed by the largest marine lives such as whales and sharks. Great white sharks, to be exact. When you think of top ocean predators, you probably think of sharks. But the true ruler of the sea is the killer whale. The open ocean has the greatest volume and vertical range of any life zone. In the open ocean, tiny organisms called (animal plankton / bacteria / decomposers / phytoplankton) perform photosynthesis. Ocean Food Chain. For example, a seal likes to eat other fish like salmon , and seals in turn can be eaten by larger animals such as orca whales. The marine food chain is one amongst them. They hunt in packs, much like wolves, which are also at the top of their food chain. Variations in light, temperature, water chemistry, nutrient continet, and pressure allow diversity of environments that are filled with a large number of species. Phytoplankton and algae form the bases of aquatic food webs. Small fish eat the shrimplike creatures, and bigger fish eat the small fish. From massive marine mammals like whales to the tiny krill that form the bottom of the food chain, all life in the ocean is interconnected. Oceanography and marine science unravels many unsolved mysteries which fascinate mankind even today. Food webs describe who eats whom in an ecological community. Hydrophobic, persistent organic pollutants such as PCBs, dioxin, and DDT are the chemicals most likely to be accumulated and efficiently transferred throughout the marine food chain. Shrimplike creatures eat the diatoms. Food Chain of the Arctic Ocean. They are the primary producers in many (ecological pyramids / food chains / food webs trophic levels) that overlap to form a(n) (ecological pyramid / food chain / food … In the ocean, you have a plant-like organism, plankton, that is floating around in the waves. Evidence of contaminated sediments, whether they are in estuaries or in open ocean areas, is found in the marine food chain. New York: Facts On File, Inc., 2008.
