<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>
do u mean microbial symbiosis?
Answer:
Symbiosis is a relationship between two organisms
Types of Interactions
Positive interaction: Mutualism, Syntrophism, Proto-cooperation, Commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation
The answer is D as there are fluctuations which means that changes in the population of one affects the population of the other. as prey pop increases predator pop increases leading to a decease in prey pop which causes predator pop to decrease due to lack of food then prey increases and the cycle repeats
