Given below are two statements. In the light of the above statements, choose the correct answer from the options given below.
Statement I:Biomagnification occurs when the toxic burden of a large number of organisms at a lower trophic level is accumulated and concentrated in organisms at a higher trophic level.
Statement II:The effects of toxins are magnified in the environment through food webs.
ABoth Statement I and Statement II are true ✓ Correct
BBoth Statement I and Statement II are false
CStatement I is true but Statement II is false
DStatement I is false but Statement II is true
Correct answer: (A) Both Statement I and Statement II are true
Explanation
Both statements are true, describing how toxins concentrate up the food chain.
Statement 1 is correct, since the toxic load of many low-level organisms accumulates in fewer higher-level ones.
Statement 2 is correct, since food webs magnify toxin concentrations at each successive level.
Persistent, fat-soluble chemicals like DDT are classic biomagnifying agents.
Top predators therefore carry the heaviest toxic burdens.
This differs from bioaccumulation, which is build-up within a single organism.
