EXPLANATION
Aquatic Biodiversity, Endangered Species & Co
- Soil and Ecological Terminology Matching:
- Cumulose material $\to$ (II) Peat: Cumulose deposits consist of partially decayed plant matter accumulating under waterlogged anaerobic bog conditions to form organic peat soils.
- Clay $\to$ (IV) Colloidal state: Clay particles possess minute particle sizes ($\lt 0.002\text{ mm}$) and immense specific surface area, behaving as inorganic soil colloids with surface negative charges.
- Biomagnification $\to$ (I) Lower to higher trophic level: Biomagnification is the progressive increase in the concentration of persistent bioaccumulative toxicants (e.g., DDT, methylmercury) across trophic levels.
- Slightly acidic/alkaline soils $\to$ (III) Cation exchanger: Functional exchange complexes of soil clays and humus hold exchangeable cations ($\text{Ca}^{2+}, \text{Mg}^{2+}, \text{K}^+, \text{Na}^+$).
- Matching Summary:
- Correct Option: Option 3.
