Consider the following statements:

1.Bioaccumulation takes place within a single organism over its life, giving a higher concentration in older individuals

2.Biomagnification takes place as chemicals move up trophic levels, giving a higher concentration at higher levels

AStatements 1 and 2 are true ✓ Correct

BOnly statement 1 is true

COnly statement 2 is true

DBoth statements are false

Correct answer: (A) Statements 1 and 2 are true

Explanation

Both statements are true, so the definitions of bioaccumulation and biomagnification hold together.

Statement 1 is right, as bioaccumulation builds up within one organism over its life, leaving older individuals more contaminated.

Statement 2 is right, as biomagnification raises concentration as chemicals pass up successive trophic levels.

One works within a single body over time, the other across the food chain, and the two often act together.

Both depend on substances that the body cannot easily break down or excrete.

Fat-soluble pollutants are especially prone to both accumulating and magnifying.
