BIO 182 EXAM 4 GCU QUESTIONS &
ANSWERS (RATED A+)
a sequence of unlearned acts directly linked to a simple stimulus - ANSWERfixed
action pattern
A chemical that acts as an alarm substance is a - ANSWERpheromone
deforestation of a watershed - ANSWERdramatically increases the flow of water and
minerals out of the watershed
The direct product of nitrogen fixation - ANSWERNH3
The phosphorous cycle lacks an ______ component - ANSWERAtmospheric
Most of the sunlight that reaches Earth __________. - ANSWERis not captured for
use by living things
Important bio geochemical cycles in ecosystems include all of the following except
the ______ cycle - ANSWERPotassium
Primary producers are - ANSWERautotrophs
The law of conservation of mass is important in ecology because - ANSWERit allows
scientists to determine the gain or loss of a chemical element in an ecosystem
An ecologist might conduct research to answer which of the following questions? -
ANSWERHow do tapeworms adapt to life in the human intestine?
The term that describes a lake that is nutrient poor and oxygen rich is -
ANSWERoligotrophic
The region that is periodically submerged between the land and the ocean is called
the _____ zone - ANSWERintertidal
After nutrient enrichment from sewage contamination, a lake often becomes
inhospitable to fish. Why? - ANSWERNutrient input to a lake causes the explosive
growth of algal and cyanobacterial populations. Decomposition of dead algae and
cyanobacteria by bacteria results in the depletion of oxygen in the water, which leads
to the death of fish.
Honeybees have a remarkable way of transferring information about the location of a
food source to other members of the hive. The worker bees conveying this
, information use __________ communication to relay this information. -
ANSWERvisual
Animals that exhibit which type of mating behavior are often so morphologically
similar that it is difficult to distinguish the sexes based on external characteristics -
ANSWERmonogamous
A cross-fostering study is a study in which - ANSWERyoung of one species are
placed in the care of adults of another species
Migratory orientations within a species are___________. - ANSWERgenetically
determined
A(n) ______ involves a response to each stimulus that is the stimulus for the next
behavior - ANSWERstimulus-response chain
Which of the following is an example of a circannual rhythm - ANSWEREvery spring
robins gather in the park to build nests and reproduce.
Which of the following best illustrates optimal foraging - ANSWERA sunbird will
defend more fiercely flowers that produce more food.
Niko Tinbergen's 4 questions - ANSWER1. What stimulus elicits the behavior, and
what physiological mechanisms mediate the response?
2. How does the animal's experience during growth and development influence the
response?
3. How does the behavior aid survival and reproduction?
4. What is the behavior's evolutionary history?
In addition to serving as a weapon, the male fiddler crabs large claw - ANSWERis
used to attract females when searching for a mate
This type of associative learning that involves trial and error is - ANSWEROperant
conditioning
This type of associative learning that Ivan Pavlov used in which he always rang a
bell before feeding a dog is called - ANSWERClassical conditioning
______ is/are critical to imprinting a long-lasting behavioral response to a particular
individual or object - ANSWERsensitive period
What signals might be best employed by a nocturnal forest animal seeking to identify
its territory? - ANSWERauditory and olfactory
Ants carry dead ants out of an anthill and dump them on a "trash" pile. If a chemical
from a dead ant is applied to a live ant, other ants will carry it, kicking and struggling,
from the anthill, until the substance wears off. Which of the following explains this
behavior? - ANSWERThe chemical is a sign stimulus for a fixed action pattern
