Explanation:
Sergei Winogradsky was a russian microbiologist. He observed in his research with genus of bacteria <em>Beggiatoa, </em>they were able to oxidize hydrogen sulfide as an energy source. Being the first example known of lithotrophs (organisms that use inorganic substrate in order to obtain energy).
Answer:
The colon.
Explanation:
The colon, also known as the large intestine is one of the major organs of the digestive system and plays a vital role in the processing of food and excretion of waste. It is divided into the ascending colon, transverse colon, descending colon and sigmoid colon.

The reason for this is that phosphorus cannot be found in the gas state, unlike the sulfur. On the other hand, sulfur cycle partially occurs in the atmosphere.</span>
