Explanation:
In the shown food web, almost all organisms are the food source for the fungus. They feed on dead organic matter. Fungi breakdown dead organic matter into basic nutrients such as derivatives of C, N, O, P, K, etc. These nutrients then act as building blocks of macromolecules amino acids, carbohydrates, fats, nucleic acids required for the biogeochemical functioning of the food web.

Fish is an example of biotic factor which is dependent on abiotic component that is oxygen which is the chief gas required for the breathing. The oxygen is one of the components of the water. So, the oxygen is dissolved in water and the fish acquire the oxygen through water only.
Molarity : It is defined as the number of moles of solute present in one liter of solution.
