The best answer is B - Proteins.
Proteins make up enzymes, or to put it another way enzymes are made up of protein. It is enzymes that speed up the chemical reactions. Enzymes are organic catalysts, substances that speed up a (biochemical) reaction but do not take part in the reaction and remain unchanged at the end of the reaction.
In man, there are many enzymes. The majority of these are found in the digestive system where they greatly aid the process of food breakdown from complex molecules to simple molecules. Examples include salivary amylase found in saliva, which begins the gradual breaking down of starch into glucose right from the moment food is placed in the mouth and mixed with saliva. Pepsin in the stomach breaks down protein.

They decompose dead organisms. Also, some fungi helps other organisms obtain nutrients that the organism cannot obtain
Explanation:
A species with a wide range of tolerance can dominate most habitats due to its ability to adapt.
<h3>What is a wide range of tolerance?</h3>
A wide range of tolerance is the ability for an organism to tolerate low or high levels of abiotic contamination in it's natural habitat. This means that the organisms in question show a high level of adaptability and are able to survive in hostile environments. This allows them to remain dominant in most habitats despite contamination values.
Therefore, we can confirm that a species with a wide range of tolerance can dominate most habitats due to its ability to adapt.
