Question

1. abyssopelagic zone after you have recorded the values of temperature, pressure, chlorophyll content, and salinity within the abyssopelagic zone, review the pressure values recorded at various depths and identify the pressure at 8000 m. 407.20 bar 805.16 bar 13. what marine organisms are commonly found in the abyssopelagic zone? octopus, hatchet fish, sperm whales mackerel, sharks, turtles giant squid, angler fish sponges and deep - sea anemones

Explanation:

1. The pressure in the ocean increases with depth. The pressure at a depth of 8000 m is approximately 805.16 bar. This is based on the hydro - static pressure formula $P = P_0+

ho gh$, where $P_0$ is the atmospheric pressure, $
ho$ is the density of seawater, $g$ is the acceleration due to gravity, and $h$ is the depth.

1. The abyssal zone is a deep - sea environment with high pressure, low temperature, and no light. Common organisms in this zone include giant squid and angler fish. Octopus and hatchet fish are not typical of the deep - abyssal zone, and sperm whales are large mammals that can dive to great depths but are not exclusive to the abyssal zone. Mackerel, sharks, and turtles are not characteristic of the abyssal zone. Sponges and deep - sea anemones are more commonly found in shallower deep - sea zones rather than the abyssal zone which is extremely deep.

Answer:

1. 805.16 bar
2. giant squid, angler fish
