Powerful Plankton
The U.S. Naval Research Laboratory has created an experimental marine fuel
cell that could produce enough electricity to power ocean-monitoring devices.
This fuel cell runs on seawater and sediment, with the help of plankton. Some
plankton on the surface of ocean sediments use dissolved oxygen to break
down organic matter, releasing energy; this is an aerobic process. The
plankton in the deeper sediments break down organic matter without using
oxygen; this is an anaerobic process. These two processes create a difference
in voltage between the surface of the sediment and the sediment farther down
in the seabed. The voltage difference can be used to produce electricity—up to
5.0×10–2 watts of power. Energy supplied by this type of fuel cell can be
obtained as long as there is organic matter in the sediment.

Save Our Species Poster: Black-Footed Ferret
This slender animal depends mainly on
prairie dogs for food and shelter. The ferret
lives in prairie dogs’ underground tunnels
and hunts them at night. When prairie dogs
became scarce, so did black-footed ferrets.
In 1986 the 18 ferrets known to be alive
were moved to a Wyoming research
institute. The number of ferrets has
increased, and recently a few were released
into managed wildlife areas.
65
According to the information above, which of these is responsible
for the decrease in the black-footed ferret population?
F
G
H
J
Competition with prairie dogs for resources
