any long, slender object. For the chicks, pecking is a _________ and the red dot is a
_______. For the adult gulls, the chicks pecking at their bills is a _______ and
regurgitating food is a ________.
A. fixed action pattern, key stimulus; key stimulus, fixed action pattern
B. key stimulus, fixed action pattern; fixed action pattern, key stimulus
C. fixed action pattern, fixed action pattern; key stimulus, key stimulus
D. key stimulus, key stimulus; fixed action pattern, fixed action pattern
5. A hummingbird is visually attracted to the red, tubular flowers of a trumpet vine. It
drinks nectar from the flower and, in doing so, inadvertently transfers pollen from one
flower to the next. In this form of communication, who is the sender, who is the receiver,
and what information is being transferred? Think carefully here...This is a question that
stumps a lot of students and it is bonus points for a reason. Look at the behaviors from
the perspectives of both the bird and the plant.
A. The flower is the sender, the hummingbird is the receiver, and the availability of
nectar is the information.
B. The hummingbird is the sender, the flower is the receiver, and the availability of the
hummingbird to transfer pollen is the information.
