-
B.
Improved soil fertility
-
C.
Enhanced aquatic ecosystems
-
D.
Increase in species diversity
Correct Answer:
A. Extinction of sensitive species
Explanation:
Pollution significantly harms biodiversity by directly damaging species and their natural habitats. Contaminants introduced into ecosystems can cause diseases, interfere with reproductive cycles, and lead to the decline or extinction of sensitive species. Furthermore, pollutants often accumulate within food chains through biomagnification, where toxin concentrations increase at higher trophic levels, resulting in severe health issues for apex predators and disrupting the overall ecological balance.
