Question

Is the carbon to nitrogen ratios in trees significantly different from the ratio in a healthy adult human? Provide an explanation of why differences may exist based on how nitrogen is used in molecular structures

Answer 1

Answer:

Yes the carbon to nitrogen ratios in trees significantly different from the ratio in a healthy adult human.

Nitrogen is a macronutrient that forms an essential integral component of plants.

Many amino acids and nucleic acids that are important in plant growth contain amine group, these amino acids are the building blocks of proteins. Chlorophyll contains nitrogen in good amounts, artificial supplementation of nitrogen containing fertilizers turn the chlorophyll to dark green. Nitrogen availability in sufficient amounts promotes the nutritional weight of the crops and also plant growth.

Nitrate fixation: Natural scavangers decompose the nitrogen containing material in order to provide nitrogen sources to a variety of living organisms by the process of nitrogen fixation. . Conversion of atmospheric nitrogen (N2) into ammonium ion is called nitrogen fixation. Nitrogen fixation from the atmosphere involves an enzyme called “nitrogenase.” Nitrogen fixation process is very important for all the living beings because it is the structural unit of many amino acids and nucleic acids. Plants can only take nitrogen in its ammonia from.

N2 + 8H+ + 6e- ----------> 2 NH3 + H2

Nitrogen fixation by soils involves the binding of positively charged ammonium to the negatively charged clay particles. In clays such as vermiculite, these ions become trapped within the holes in the crystal structure; this process is called as ammonium fixation. Ammonium conserved in these holes is slowly released to plants.

Soils also contain a variety of organisms that are involved in nitrogen fixation. Mainly prokaryotic organisms such as many bacteria, Rhizobium species, actinomycetes and cyanobacteria are involved in nitrogen fixation process.

Nitrogenous base synthesis (DNA and RNA) macromolecular structures:

Nucleotide structure = Nitrogenous base + deoxy or oxy ribose (pentose) sugar + phospho diester bond

Impact of leaf litter and Nitrogen fertility of soil:

The most crucial aspects of plant R. catharica is the changing the surrounding ecosystem by inducing effects such as nitrogen and carbon cycling through the process of decomposition. These leaf litters possess higher content of nitrogen and thereby they can induce greater nitrogen fixation. Heneghan et al. (2002) have experimentally concluded that the nitrogen and carbon fixation in soil is greater compared to the Populas deltois species. Heneghan et al. (2002) Proved and illustrated through his research findings i.e. the decomposition rates are lesser where there is lesser abundance of earth worms and buckthorns. Higher availability of earthworms and buckthorns improves soil % nitrogen and % carbon with greater gravimetric water content result in good fertility of soil for habitat growth.
