Why must kelp live in deep, calm waters?
nutrients are more abundant in deep, calm waters than in warm, turbid waters
the photosynthetic pigments of kelp are more efficient in the depths than in the shallows

Industries have built many oil and gas platforms off the Texas coast. Coral reefs have formed underwater on many of the platforms. The formation of coral reefs on the platforms is -
harmful because it increases competition between coral reefs
harmful because it decreases the likelihood that coral reefs will form in flat, muddy areas
helpful because it offsets the number of coral reefs lost to pollution
helpful because it prevents coral reefs from forming in flat, muddy areas
What is an invasive species?
An organism that is new to an environment that has positive effects on the environment.
An organism that is native to an environment that has negative effects on the environment.
An organism that is new to an environment that has negative effects on the environment.
An organism that is native to an environment that has positive effects on the environment.

It's hard to reduce lionfish numbers because _______.
they often live in spots where divers can't reach them.
they have spines that keep predators from eating them.
they reproduce quickly.
all of the above.
