Answer

hydrothermal vent

Answer

Answer

the vent fluid

Question 9

Accepted Answer

2 degrees Celsius

Answer

Answer

8 degrees Celsius

Answer

20 degrees Celsius

Question 10

Accepted Answer

copper, zinc and iron

Answer

magnesium , calcium, iron

Answer

barium, calcium, silicon

Answer

iron sulfide

Question 11

I live in the outer boundary of the hydrothermal vent . I prefer temps of 2 degrees Celsius. I am whitish orange with big elephant ears on the side . I have a powerful beak and am a top predator. What animal am I ?

Accepted Answer

octopus

Answer

clam

Answer

tubeworm

Answer

mussel

Question 12

Hot liquids are less dense and therefore more buoyant than cold liquids

Accepted Answer

True

Answer

False

Question 13

I live around hydrothermal vents along the Mid-Ocean Ridge in the Eastern Pacific Ocean. I can grow up to two meters long and ten centimeters in diameter. I am made of a hard material called chitin, which protects me from the toxic vent chemicals and from predators such as crabs and fish. I do not eat because I don't have a mouth nor a stomach. Instead, billions of symbiotic bacteria living inside me produce sugars from carbon dioxide, hydrogen sulfide, and oxygen. I use some of these sugars as food. What animal am I

Accepted Answer

Tubeworm

Answer

mussel

Answer

squat lobster

Answer

anemone

Question 14

These two-foot long white fish are top predators around vents. They eat everything from tubeworms to shrimp. Despite their huge appetites, these fish are slow and lethargic. They spend a lot of time floating around clumps of tube worms and mussels

Accepted Answer

zoarcid

Answer

shrimp

Answer

tubeworm

Answer

clams

Question 15

Where do the hot water and chemicals for hydrothermal vent ecosystems come from?

Accepted Answer

fractures in the oceanic crust where water meets magma

Answer

the shelf break

Answer

hot waste water from nuclear plants

Answer

climate change

Question 16

Large tube worms over six feet long are one of the most visible animals at the vents. These tube worms, secrete a thick paper-like white tube along their body. The worm does not have a mouth or gut instead they rely on bacteria living in their tissues to produce the 'cell food' needed to keep them alive. It is believed these worms are some of the fastest growing invertebrates known. Name the type of symbiotic relationship between the bacteria and tubeworm

Accepted Answer

mutualistic

Answer

parasitic

Answer

commensalism

Question 17

What gives the hydrothermal fluid the appearance of smoke

Accepted Answer

The fluid carries dissolved metals from deep beneath the ocean floor. When the fluid mixes with sea water, these metals combine with sulfur to form tiny black particles. These particles make the fluid look like smoke.

Answer

The fluid carries dissolved bacteria from deep beneath the ocean floor. When the fluid mixes with sea water, these bacteria combine with sulfur to form tiny black particles. These particles make the fluid look like smoke.

Answer

The fluid carries dissolved from animal debris deep beneath the ocean floor. When the fluid mixes with sea water, the debris combine with sulfur to form tiny black particles. These particles make the fluid look like smoke.

Question 18

Which has a hotter temperature, the white smoker or the black smoker ?

Accepted Answer

black smoker

Answer

white smoker

Answer

neither
