D) phosphorus cycle E) C and D The burning fossil is a significant contributor to the world's A) water cycle B) carbon cycle C) nitrogen cycle. D) phosphorus cycle E) C and D Which of these nutrients cycle are affected by the large-scale clear cutting of tropical rain forests? A) carbon cycle B) nitrogen cycle. C) phosphorus cycle D) all of the above E) none of the above Molecules that lack carbon to carbon and/or carbon to hydrogen bonds are said to be A) organic.

Explanation / Answer

Question 1) option d) aerobic respiration

Reason : aerobic respiration is the biotic process that returns inorganic carbon to the atmosphere from the equation Aerobic respiration is the form of respiration which uses oxygen which can be written as glucose + oxygen carbon dioxide + water (+ energy)

Question 2) E) denitrification

Reason: Denitrification is the process in which reduction of nitrates is done back into nitrogen gas (atmospheric nitrogen)

Question 3) option E)

Reason : the manufacture of synthetic fertilisers plays a very important role in nitrogen and Phosphorus cycle

Question 4) option b) carbon cycle

Reason : burning of fossil fuels lead to the increase of Carbon dioxide levels in atmosphere . Thus it is a significant contributor to carbon cycle

Question 5) option D)

Reason : The phosphorus cycle is affected due to deforestation. When trees are removed, soil levels of phosphorus are reduced .Deforestation causes a decrease in organic nitrogen in an area and also the carbon cycle is also affected
