Freshwater ecosystem type is the factor that does not determine the strength of a toxic in an aquatic ecosystem.
- A toxin is a substance which is responsible for causing detrimental effects on the body of the living organisms.
- The excess dose of toxin can produce lethal effects in living beings.
- The strength of the toxin is determined by its amount or concentration in the water body more the amount or concentration of toxin the more will be its strength.
- The strength of toxin can be determined by its absorption in the aquatic organisms like gills of fishes more the absorption more will be the strength and more will be the impact.
- The strength of toxin can also be determined by the mutation it can cause more the number of mutation it can cause more lethal will be the effect.
- The freshwater ecosystem is a source of freshwater which will be free from saline water. It can be a river, lake, pond, or others.
- It does not matter which type of freshwater ecosystem is affected by the toxin. If the toxin is able to mix with the water then it can be absorbed by the aquatic organisms and the toxin will exert its negative effects.
- Hence, freshwater ecosystem type is the correct option.
