Above: In a light sensor, the electrical circuit consists of a great many parts. If just one is
removed or only one connection altered, the circuit fails to work. The light sensors in
plants possess a feature similar to this circuit: The slightest deficiency in the system will
make the sensor totally useless.

that detect light intensity changes, and use them in lamps that go on when
it gets dark at night and turn themselves off at dawn. 124
The Eider Duck and Its Insulation System
Our bodies generate heat energy by digesting the food we’ve eaten
during the day. The best way to prevent the loss of this warmth is to keep
it from leaving our bodies too soon. That is why we wear varying layers
of clothing, depending on the
weather. Warm air, trapped be-
tween the layers, is unable to reach
outside. Preventing energy loss in
this way is known as insulation.
The eider duck employs the
exact same method. Like many
birds, its feathers enable it to fly
