<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>

Answer:
DDWw x Ddww
DdWw x DDww
DDWw x DDww
Explanation:
D for tallness
d for dwarfness
W for violet
w for white
For Parental Plants that has
tall, violet x tall, white
The representation will be
DDWW × DDww (We the apply the mendelian crossing)
This will yield offsprings with the following trait
DDDD × DwDw
DDDD × DwDw
DWDW x WwWw
DdWw x ddww
Ddww x ddWw
DdWw x DdWw
DDWw x ddww
From the above Offsprings
1/2 tall, white and 1/2 tall, violets offspring are
DDWw x Ddww
DdWw x DDww
DDWw x DDww
