1) pathogen enters body and releases chemoattractants
2) a phagocyte/macrophage is attracted by these chemicals
3) the phagocyte engulfs the pathogen using its pseudopodia
4) the membranes of both organisms fuse forming a phagosome
5) lysosomers in the phogocyte fuse with the phagosome, forming a phagolysosome
6) these enzymes digest the pahogen (hydrolyse the bonds)
7) the antigens of the pathogen are placed on the surface of the phagocyte making an APC (antigen presenting cell)
<u>Answer:</u>
<em>Reduction of sulfur compounds and the release of hydrogen sulfide is happening here.</em>
<u>Explanation:</u>
Sulfur is an important element in the sulfur cycle. Sulfur compounds can be found on earth in various forms. They can be found in mineral rocks and organic matter. It is the <em>work of bacteria to reduce sulfur</em> compounds and convert them to sulfides.
There are different types of bacteria that reduce various sulfur containing compounds. They are <em>sulfate-reducing bacteria, sulfur-reducing bacteria, sulfite reducing bacteria etc.</em> In a swamp there is low oxygen availability and organic matter decays in this condition.
<em>The sulfate reducing bacteria oxidizes the organic matter and releases Hydrogen sulfide.</em>
Trophic pyramid, also called an energy pyramid, showing the progression of food energy. The pyramid base contains producers, organisms that make their own food from inorganic substances. ... Thus, the higher the trophic level on the pyramid, the lower the amount of available energy.
