Give Five Disadvantages of Organic Fertilizers.

(a)              The total concentration of dissolved inorganic carbon in a sample of sedimentary pore water is 5.576 mmol/kg. Isotopic analysis of this DIC yields a δ¹³C = -37‰ vs. PDB. It’s known that the pore water initially contained some CH₄ with δ¹³C = -84‰ vs. PDB, that the CH₄ has been converted quantitatively to CO₂, that pore waters in which no CH₄ was oxidized have δ¹³C = -12‰ vs. PDB, and that the pore water in question has neither lost nor gained DIC except by the oxidation of CH₄. What were the initial concentrations of dissolved inorganic carbon and CH₄ in the pore water? 

In 1882, Theodor Engelmann performed an important experiment in regards to photosynthetic activity.

What Engelmann did was to place oxygen seeking bacteria and algae (single celled photosynthetic organisms) on a microscope slide. He illuminated the slide through a glass prism. The prism splits white light into the various wavelengths of light so that each section of the slide was receiving a different wavelength/color of light. At the end of the experiment, he observed the following under a microscope, as demonstrated in the figure below.

a. What was Engelmann’s hypothesis about photosynthesis that formed the basis of the above experiment?

b. What are the various observations from the above experiment (based on the figure)?

c. What could be the possible conclusions from the above experiment?

d. What possible additional experiments would you suggest to exclude the possibility that the bacteria are attracted to the blue and red lights?
