Solution

The correct option is A 1-b-iii; 2-c-i; 3-a-ii
Marine ecosystem is divided into three different zones based on the availability of light at different depths:
i) Euphotic zone/sunlit zone
ii) Bathyal zone/twilight zone
iii) Abyssal zone/dark zone
Oceanic zones have variations in temperature, pressure, light, etc. These abiotic factors give rise to various adaptations in organisms in the different zones.
