Aquatic Ecosystem - 9195 Words

Aquatic ecosystem An estuary mouth and coastal waters, part of an aquatic ecosystem. An aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. What is an aquatic ecosystem? Aquatic systems are those that contain plants and animals that predominantly depend on a significant amount of water to be present for at least part of the year. But a perfect definition is tough to make. How many weeks a year does an area need to show standing water in order to be a pond? How about a bird bath or dog water dish, as both can breed aquatic insects†¦show more content†¦Ã¢â‚¬ ¢ Lotic: rapidly-moving water, for example streams and rivers. †¢ Wetlands: areas where the soil is saturated or inundated for at least part of the time. Lake ecosystems can be divided into zones: pelagic (open offshore waters); profundal; littoral (nearshore shallow waters); and riparian (the area of land bordering a body of water). Two important subclasses of lakes are ponds, which typically are small lakes that intergrade with wetlands, and water reservoirs. Many lakes, or bays within them, gradually become enriched by nutrients and fill in with organic sediments, a process called eutrophication. Eutrophication is accelerated by human activity within the water catchment area of the lake. [pic] Freshwater ecosystem. The major zones in river ecosystems are determined by the river beds gradient or by the velocity of the current. Faster moving turbulent water typically contains greater concentrations of dissolved oxygen, which supports greater biodiversity than the slow moving water of pools. These distinctions forms the basis for the division of rivers into upland and lowland rivers. The food base of streams within riparian forests is mostly derived from the trees, but wider streams and those that lack a canopy derive the majority of their food base from algae. Anadromous fish are also an important source of nutrients. Environmental threats to rivers include loss of water, dams, chemical pollution and introduced species.Show MoreRelatedDescription Of Aquatic Ecosystems : The Aquatic Ecosystem1210 Words   |  5 PagesDescription of Aquatic Ecosystems The aquatic ecosystem is a vital part of the Earth’s vigorous process and is indispensable for a sustainable Earth and its inhabitants.

According to the â€Å"Alternative stable state theory† ecosystem has various states and can switch from one state to another when ecosystem conditions are changing (Holling, 1973; Scheffer, 2001). When the magnitude of such disturbance is negligible, the shift in the ecosystem structure and functioning does not occur. In this case the ecosystem resilience allows it to returnRead More How Acid Rain Affects the Aquatic Ecosystem Essay1387 Words   |  6 PagesHow Acid Rain Affects the Aquatic Ecosystem Abstract This paper shows that acid rain is a reality.

Once a reservoir is built it immediately impacts a fish community by changing habitat quality and the flow regime. The main impact that dams have on aquatic ecosystems is the change of flow regime from lotic to lentic (Agostinho 2008). Lotic systems are typically categorized as free-flowing systems examples of these are rivers and streams. Lentic systems can be classified as sedentary systems because theyRead MoreThe Increasing Threat from Mercury in Our Aquatic Environment1677 Words   |  7 PagesMercury contamination in aquatic environments is becoming an increasing threat to both wildlife and humans (Peterson S.

How to Study for a Test or Final Exam

The end of the term is drawing near, and that means final exams are looming. How can you give yourself an edge this time around? The most important thing you can do is give yourself plenty of time to prepare. Then follow this simple plan: 1) Study2) Test yourself with a practice test3) Discover your weak areas4) Study again5) Test yourself again That’s the simplified version. For really great results on your finals: Science Says Start Early There are many recent studies that show  that it is important to study in stages. The findings say that its best to  start early and give your brain a rest, then study again. If youre preparing for a comprehensive exam, gather together all the material you’ve received during the term. You probably have handouts, notes, old assignments, and old tests. Don’t leave anything out. Read through your class notes twice. Some things will sound familiar and some things will sound so unfamiliar you’ll swear they were written by somebody else. That’s normal. After you study all your notes for a term, try to come up with themes that connect all of the material. Establish a Study Group or Partner Schedule at least one meeting time with a study partner or study group. If you absolutely can’t get together, then exchange email addresses. Instant messages will work well, too. Invent and use learning games with your group. You could also consider communicating through an online forum like the Homework / Study Tips forum. Use Old Tests Collect your old exams from the year (or semester) and make a photocopy of each one. Whiteout the test answers and copy each one again. Now you have a set of practice tests. For best results, you should make several copies of each old exam and keep taking the tests until you score perfectly on each one. Note: You can’t white out the answers on the original, or you won’t have an answer key! Build Up Your Class Notes Organize your notes by date (do the best you can if you didn’t date your pages) and make note of any missing dates/pages. Get together with a study partner or group to compare notes and fill in any missing material. Don’t be too surprised if you missed key information from the lectures. Everybody zones out once in a while. After you organize your new set of notes, underline any keywords, formulas, themes, and concepts. Make yourself a new practice test with fill-in sentences and term definitions. Print out several tests and practice several times. Ask the members of your study group to make practice tests as well. Then swap. Re-Do Your Old Assignments Gather any old assignments and re-do the exercises. Many textbooks have exercises at the end of every chapter. Review those until you can answer every question with ease. Use Different Textbooks If you’re studying for a math or science exam, find another textbook or study guide that covers the same material that you’ve studied this term. You can find used books at yard sales, used book stores, or in the library. Different textbooks will provide you with different explanations. You might find one that makes something clear for the first time. Other textbooks can also give you a new twist or fresh questions on the same material. Thats exactly what your teacher will do on the final! Invent Your Own Essay Questions For history, political science, literature, or any theory class, focus on themes. Read your notes again and mark anything that looks like it would serve well as an essay question. Which terms make good comparisons? For example, what terms could a teacher use as a â€Å"compare and contrast† question? Try coming up with your own long essay questions by comparing two similar events or similar themes. Have your friend or study partner come up with essay questions and compare.

Illness Through The Eye Of The Beholder - 1425 Words

Illness Through the Eye of the Beholder Because identities are both externally prescribed and internally experienced, it is crucial that we evaluate the methodology by which medical professionals identify and treat illnesses. At the point where suffering is unique to each individual, it is important that we also consider the tools that each person has to describe their symptomology, as to elucidate their suffering in the context of the clinical perspective so that appropriate resources and treatments would be made available to them. One such methodology used to understand illnesses is known as the â€Å"illness narrative† in which Dr. Arthur Kleinman describes in his book, The Illness Narratives, as â€Å"[An] alternative therapeutic approach [originating] in the reconceptualization of medical care as (1) empathic witnessing of the existential experience of suffering and (2) practical coping with the major psychosocial crises that constitute the menacing chronicity of that ex perience† (10). Kleinman argues that this type of engagement between the doctor and the patient is key to the recovery process of the patient. However, his argument relies on one, the effectiveness of empathy through storytelling within the doctor-patient relationship, and two, the ability of the doctor to fully understand the illness experience depicted by the patient. These two implicit assumptions are contested by Toni Morrison in her novel, Home, where she asserts that we cannot fully empathize with another’sShow MoreRelatedThe Causes and Effects of Stress1901 Words   |  8 Pages â€Å"Beauty is in the eyes of the beholder†.
