Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.

Statement I:Rivers and lakes that have low biological productivity are said to be atrophic.

Statement II:Rivers and lakes that are rich in organisms and organic materials are called oligotrophic.

ABoth Statement I and Statement II are true

BBoth Statement I and Statement II are false ✓ Correct

CStatement I is true but Statement II is false

DStatement I is false but Statement II is true

Correct answer: (B) Both Statement I and Statement II are false

Explanation

Statement 1 is wrong, because water bodies with low biological productivity are called oligotrophic, not atrophic.

Oligotrophic lakes are clear, oxygen-rich and low in nutrients.

Statement 2 is wrong, because waters rich in organisms and organic matter are called eutrophic, not oligotrophic.

Eutrophic waters are nutrient-heavy and prone to algal blooms.

Both statements swap or misname the trophic categories.

Excess nutrient input driving eutrophication is called cultural eutrophication.
