Vedclass · Answer

(B) In aquatic habitats,light zonation occurs in deep lakes and oceans based on light penetration:$(i)$ Euphotic Zone $(A)$: This is the uppermost layer where light intensity is sufficient for photosynthesis to exceed respiration. It receives the most sunlight.$(ii)$ Disphotic Zone $(B)$: This is the intermediate layer (twilight zone) where light intensity is low,often at or below the compensation point,limiting photosynthetic activity.$(iii)$ Aphotic Zone $(C)$: This is the deepest layer where light does not penetrate,resulting in perpetual darkness. Photosynthesis cannot occur here.Based on the provided diagram,$A$ represents the Euphotic zone,$B$ represents the Disphotic zone,and $C$ represents the Aphotic zone. Therefore,the correct option is $B$.

Identify $A, B$ and $C$ in the given diagram.
