Question

part 4: data interpretation

1. pressure calculation:

for every 10 meters you descend, pressure increases by 1 atmosphere (atm).

• if a submersible is sitting in the abyssopelagic zone at 5,000 meters, how many atmospheres of pressure are acting on the hull?
• calculation: $5,000 / 10 = \text{______ atm}$

1. adaptation match:

match the adaptation to the correct zone:

1. countershading (dark top/light bottom) ____
2. bioluminescent lures (light in the dark) ____
3. holdfasts (clinging to rocks during waves) ____

• a. intertidal zone
• b. epipelagic zone
• c. bathypelagic zone

Explanation:

Step1: Calculate pressure at 5000m

$\frac{5000}{10} = 500$ atm

Step2: Match adaptation to zone

1. Countershading: Epipelagic Zone (B)
2. Bioluminescent lures: Bathypelagio Zone (C)
3. Holdfasts: Intertidal Zone (A)

Answer:

1. 500

9.

1. B. Epipelagic Zone
2. C. Bathypelagio Zone
3. A. Intertidal Zone
