Average the following give zones of the pelagic region of an ocean in the increasing order of its depth from
1. Mesopelagic
3. Abyssopelagic
2. Epipelagic
4. Bathypelagic
5. Hadopelagic
Choose the correct cthswer f{oril the options given below:
5, 1, 4, 3, 2
Incorrect Answer2, 1, 4, 3, 5
Correct Answer1, 2, 5, 3, 4
Incorrect Answer4, 1, 2, 5, 3
Incorrect AnswerExplanation:
- The pelagic zones of the ocean from shallowest to deepest are:
- Epipelagic (surface to ~200 m): Sunlit zone where photosynthesis occurs.
- Mesopelagic (200–1,000 m): Also called the twilight zone, little light penetration.
- Bathypelagic (1,000–4,000 m): No sunlight, pitch dark.
- Abyssopelagic (4,000–6,000 m): Near the ocean floor, cold, high pressure.
- Hadopelagic (>6,000 m): Deep ocean trenches, the deepest part.
- Your provided Option: 2, 1, 4, 3, 5 orders them as:
- 2. Epipelagic
- 1. Mesopelagic
- 4. Bathypelagic
- 3. Abyssopelagic
- 5. Hadopelagic
- This matches the correct increasing order of depth for pelagic zones.
Option:2, 2, 1, 4, 3, 5 is the correct answer.
