they eat plankton: the small and microscopic organisms drifting or floating in the sea or freshwater‚ consisting chiefly of diatoms‚ protozoans‚ small crustaceans‚ and the eggs and larval stages of larger animals. Many animals are adapted to feed on plankton‚ especially by filtering the water. There are different types of animals that eat different things‚ most of the ocean fish usually eat each other‚ as well as crustaceans such as shrimp‚ and crabs. Fish also eat kelp‚ algae‚ and plankton‚ as well

Food chains‚ Food Webs and the Flow of Energy in Ecosystems Introduction An ecosystem can be defined as a more or less self-contained function unit in ecology consisting of all abiotic and biotic interactions in a specific area. Flow of energy within an ecosystem is a one-way process; Photosynthesis utilizes light (solar) energy to yield chemical energy that is passed on to organisms at significantly reduced amounts at each level of nutrition. This ‘inefficiency’ in energy transfer is the principal constrain

They are usually at low altitudes in slow flowing water. Besides plankton‚ they also feed on eggs of native species. In other words‚ they not only eat the food of their competition‚ but they also eat the competition before it can

Henessey Gonzalez October 24‚ 2013 Shark Finning is Inhumane Every year millions of sharks die a slow and immoral death from fishermen stripping them of their fins. These fish are taken out of the ocean and then stripped of their fins where their carcasses are then thrown back into the sea to either starve to death‚ be eaten by other predators‚ or drown because of the lack of constant movement their gills cannot extract oxygen from the water which is not only cruel but unorthodox. With that said

* A food chain shows how each living thing gets food‚ and how nutrients and energy are passed from creature to creature. Food chains begin with a plant-life‚ and ends with an animal-life Parts of the Food Chain * Producers These include all green plants. Plants are called producers. This is because they produce their own food! They do this by using light energy from the Sun‚ carbon dioxide from the air and water from the soil to produce food - in the form of glucose/sugar. These are also

ocean all the way to the bottom. They dive to the bottom to eat clams‚ snails‚ crabs‚ shrimp‚ and worms (Walrus Latest To Be Threatened By Warming). Diminished sea ice and warmer water decreases plankton‚ which those animals the walruses feed on need in order to survive. When those animals cannot feed off plankton because they are not existent‚ the walruses starve and are impacted severely. An adult walrus can eat 200 pounds of clams a day. If the walrus population stays 30 miles inshore‚ they can over

composition depends on currents‚ predators‚ herbivores and weather. To study the inshore recruitment of barnackles they took probes of the klep beds inshore and offshore and analyzed the density of plankton throughout the year. Those Probes showed that during spring and summer the concentration of plankton was way more abundant than throughout the winter. In the offshore kelp beds the B.
