Types of Biogeochemical Cycle Biogeochemical cycle is crucial for every living organism on Earth. It is strongly influenced by life forms, especially plants and microorganisms. A biogeochemical cycle can be defined as a continuous pathway by which conversion and circulation of chemical nutrients through both biotic and abiotic compartments of Earth (Butcher, 1992). Generally, biogeochemical cycles can be classified into three major categories which are nitrogen cycle, sulfur cycle and carbon cycle (Refer to Figure 1 in Appendix 1). First type of biogeochemical cycle is nitrogen cycle. Nitrogen is abundant and chemically inert gases, constitutes of about 78% of the atmosphere. According to Stevenson and Cole (1999), accumulation in soil happens through microbial fixation of nitrogen in the presence of ammonia, nitrate and nitrite; depletion exists in the process of crop removal, leaching and volatilization. In term of that, the process of releasing compound during decomposition is called mineralization. Mineralization process is carried out by the microorganisms in which it releases carbon, and also ammonium (Sprent, 1987). As a result, many kinds of organic reduce nitrogen present, like urea, organic bases, such as purines and pyrimidines, and amino compounds. Animals have nitrogenous wastes and will eventually produce lots of nitrogen (Sprent, 1987). Several pathways are illustrated throughout the nitrogen cycle, such as nitrogen fixation, ammonification, nitrification and denitrification. Gates (1921) state d that the process of converted gaseous nitrogen into ammonia or ammonium is nitrogen fixation, while ammonium can also be produced through the decaying of nitrogenous organic substance, which is called ammonification. Afte... ...ut slowly uptake of carbon dioxide from the atmosphere (Zepp, & Sonntag, 1995). Hanson, Ducklow and Field (2000) mention that in the ocean, some of the carbon taken up by phytoplankton in order to make shells of calcium carbonate that settles to the bottom of the sea to form sediments. In geological carbon cycle, carbonic acid combines with magnesium and calcium in the Earth's crust to form insoluble carbonates. Carbon dioxide reacts with some minerals to form limestone, then dissolves by rainwater and carries to the oceans. Once there, it can precipitate out of the ocean water and form layer of sediments on the sea floor. The limestone melts and reacts with other minerals under high heat and pressure far below the Earth's surface by releasing carbon dioxide. The carbon dioxide is then back into the atmosphere through volcanic eruptions (Lockwood, & Hazlett, 2010).

A Case of identity Essay

Through a comparison of ‘A Case of identity’ and ‘The Stolen Cigar case’ discuss how successful Bret Harte is in parodying Sir Arthur Conan Doyle.  There are two forms of detective story: there is the ‘who dunnit’ idea in which gentlemen detectives are called upon in all sorts of impossible situations, but always manage to solve the crime. In this type, the reader has a good idea of who committed the ‘crime’; however, the characters in the story don’t. The other type of story is a mystery, in which neither reader nor investigators know who is responsible for the crime; together with the characters, the reader too is invited to figure out the sequence of events. In the Sherlock Holmes stories the focus is on the character of the detective himself (Sherlock Holmes) and follows the story of him solving a mystery. Sherlock Holmes (S.H) was a legendary figure as he was the very first fictional detective; his stories were written in the Victorian times by the writer Sir Arthur Conan Doyle.  The S.H stories have many common features. For example S.H is seen to be very well organised and by the end, his efforts have concluded in solving the mystery/crime. This has made it easier for Bret Harte to parody Conan Doyle’s style; he uses many similar features like the same old fashioned language and also in having Sherlock Holmes or Hemlock Jones (as he is called in the parody), portrayed as a very precise, eccentric detective. In the original story, we are told of how Miss Mary Sunderland goes to S.H to find Mr Hosmer Angel-her missing bridegroom-who disappeared on the day of their wedding. S.H manages to find this man, so uncovering the fact that it is her step-father in disguise!  In the parody; ‘The Stolen Cigar Case’, Hemlock Jones (H.J) accuses Watson of stealing his cigar case and constructs an elaborate/exaggerated story to prove his point, only to find he had misplaced it! In ‘A Case of Identity’ Watson is the narrator, who, as he is some what naà ¯Ã‚ ¿Ã‚ ½ve, has to have things explained to him; this assists the reader. He tries to work out S.H’s process of deduction, often unsuccessfully, so S.H explains in a straightforward manner through Watson to the reader. He takes the role of the pupil and is a necessary link between Sherlock and the reader. As we look at things from Watson’s point of view we are able to see how S.H unravels the cases and solves the crimes. S.H is admired greatly by Watson; likewise readers also come to admire him as an exponent of ratiocination. Throughout the story, the impression is given that S.H’s previous clients have all been people high up in society as he had â€Å"a little souvenir from the king of Bohemia† in return for Sherlock helping him with a case. He has many valuable belongings, many of which have been gifts from wealthy clients of his such as his â€Å"snuff-box of gold†.  He also refers to similar cases to the ones he is working on â€Å"You will find parallel cases, if you consult my index, in Andover in ’77†. This also shows that he is an experienced detective with a powerful memory and someone in whom one can have faith.
