Question 22

A marine biologist tests a tissue sample from a bluefin tuna, an upper-level predator, for pollutants and detects high levels of mercury. She then tests a tissue sample from a basking shark, a plankton feeder, and discovers the basking shark contains low levels of mercury. Why would the basking shark contain less mercury than the Mako shark, despite the fact the basking shark is much larger than a tuna?

Accepted Answer

The mercury is higher in the bluefin tuna is due to biomagnification, because tuna feeds near the top of the food pyramid while the basking shark feeds near the bottom

Answer

Bigger animals such as the basking shark are better at metabolizing and getting rid of toxins

Answer

The basking shark's ampullary organs enable it to detect and avoid plankton contaminated with mercury

Answer

Toxins become less concentrated with a larger body size.

Answer

the lake filling in with silt as it ages

Question 25

The stream indicated at letter "B" is labeled as a 3rd-Order stream. Is this correct, and why?

Accepted Answer

Yes, because a 3rd-Order stream with a 2nd-Order stream feeding into it would still be classified as a 3rd-Order stream.

Answer

No, because a 3rd-Order stream with a 2nd-Order Stream feeding into it should be labeled as a 4th-Order stream.

Answer

Yes, because three 2nd-Order streams make a 3rd-Order stream.

Answer

No, because it is a 3rd-Order stream with a 2nd-Order feeding into it, so it should be labeld a 5th-Order Stream.

How can an intermittent stream still contain water?

Accepted Answer

Water can still flow through the porous substrate underneath the dry streambed

Answer

They cannot contain water, which is why they're dry

Accepted Answer

Sensitive species are gradually replaced by tolerant species.

Answer

The fish communities will eventually die out

Answer

The fish communities are static and do not change, regardless of the lake's trophic state

Answer

The fish grow larger as a result of more nutrients in the water

Question 35

This depthfinder scan on a lake during the summer shows a school of fish at a depth of approximately 30 feet (the blue marks at the right of the screen). Despite the warm surface temperature, why aren't the fish deeper where the cooler hypolimnion would be more comfortable?

Accepted Answer

The hypolimnion has no oxygen due to bacterial activity in the benthic zone

Answer

The hypolimnion is also the aphotic zone and contains no light for the fish to see

Answer

The hypolimnion is too deep for photosynthesis to occur, and therefore no oxygen is present

Answer

The fish avoid the hypolimnion because there's no food for them there.
