many organisms that undergo chemosynthesis use instead of to fuel the processes that convert carbon dioxide into sugars.

OLEGan [10]

Answer:

Many organisms that undergo chemosynthesis use hydrogen sulphide (H2S) instead of sunlight to fuel the processes that convert carbon dioxide into sugars.

Explanation:

Prokaryotic microorganisms, principally bacteria and archaea (referred to as “bacteria” in the following), carry out chemosynthetic reactions. Energy is produced in chemosynthetic reactions from oxidizing reduced compounds.

Chemosynthesis is the conversion of carbon (usually carbon dioxide or methane) into organic matter using inorganic molecules (hydrogen or hydrogen sulphide) or methane as an energy source. Most energy is initially derived from sunlight via plant photosynthesis. Example, bacteria and methanogenic archaea living in deep sea vents

Deoxyribose Glucose Guanine Phosphate Ribose

Sergeu [11.5K]

There is no attached table, so it could not be told precisely which of the four molecules is the DNA. But, it is known that DNA consists of deoxyribose, guanine, and phosphate.
The base unit of DNA is called a nucleotide. The nucleotide consists of a nucleobase (adenine - A, thymine - T, cytosine - C, and guanine -G), a monosaccharide deoxyribose, and a phosphate group. By knowing this, it is easy to choose which molecule of those is the DNA.
