Biotic factor is one of the component of the ecosystem. It is the living component of the ecosystem. It is affected or influenced by the non-living or abiotic components of the ecosystem like water, air, sunlight, and others. 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.
A solution with a Ph of 2 has a H+ ion concentration that is two times greater than a solution with a ph of 4. The Ph of 2 and 4 indicate that the solution is acidic since they are less than PH of 7. The H+ ions are more present when the solution is acidic but the Ph differ with concentration H+ ions. The solution with a Ph of 2 has more H+ than the solution with Ph of 4 thus the solution with Ph of 2 has more hydrogen ions than that of 4
