Causes of eutrophication:
The main causes of eutrophication are
natural run-off of nutrients from the soil and the weathering of rocks
run-off of inorganic fertiliser (containing nitrates and phosphates)
run-off of manure from farms (containing nitrates, phosphates and ammonia)
run-off from erosion (following mining, construction work or poor land use)
discharge of detergents (containing phosphates)
discharge of partially treated or untreated sewage (containing nitrates and phosphates)
In most freshwater lakes the limiting nutrient is phosphorus, so an input of phosphorus in the form of phosphate ions (PO43-) results in an increase in biological activity.
Answer + Explanation:
The definition of allusion is a brief and indirect reference to a person, place, thing or idea of historical, cultural, literary or political significance. (Allusion)
In the same way that readers can understand metaphors, words that have meaning beyond their literal interpretation, they can also understand allusions—it’s the same basic psychology. In fact, for well constructed metaphors and well constructed allusions, this process of knowing the other meaning or greater subject surrounding these words is subconscious; it happens instantly and naturally.
Authors are able to evoke certain images and memories in their readers by describing something in passing.
First, there may not be room or time. Second—and I think, more importantly—<u>using allusions allows the reader to do quick and subconscious deduction, which involves them more in what they are reader and may even give a sense of cleverness</u>.
Third is that it simply is <u>fun and rewarding to find hidden things</u>. In order to find allusions, the reader (in case of textual allusions) needs to know to what the author alludes.
Also there are <u>issues which an author may not want to address directly</u>. The author may (for various reasons) want to be unclear. By addressing issues via an allusion, the author shifts the responsibility for interpreting his thoughts to the reader.
Answer:
hyperbole ~ exgerration
imagery ~ using five senses to create a mental picture
alliteration ~ repeating the same sound at the start of each word.
