Answers
A series of reciprocal adaptations in predator and prey populations describes ________ -

CORRECT ANSWER - Pursuing
The resemblance of a harmless fly to a bee is an example of ______ - CORRECT
ANSWER - mimicry
The resemblance of the walking stick insect to a twig is an example of - CORRECT
ANSWER - camouflage
What, if any, is the adaptive value to a foxglove plant of producing a chemical called digitalis? -
CORRECT ANSWER - digitalis serves as a defense against predation
What is a necessary ingredient for competition? - CORRECT ANSWER - limited resource
According to the competitive exclusion principle, two species cannot continue to occupy the
same - CORRECT ANSWER - ecological niche
If an overlap develops between the ranges of two species that occupy the same niche in the zone
of overlap, what will probably happen in the zone of overlap? - CORRECT ANSWER -
one species will take over most or all of the zone of overlap by using the resources more
efficiently
, A territory is most likely to be defended against - CORRECT ANSWER - individuals
belonging to the same species
The evolution of adaptations that enable similar species to coexist in a community is called -
CORRECT ANSWER - character divergence
A symbiotic relationship where both of the co-existing species benefit from the interaction is
called - CORRECT ANSWER - mutualism
Commensalism describes a type of species interaction where - CORRECT ANSWER - one
species benefits and the other is unaffected by the interaction
Parasites are different from predators in that - CORRECT ANSWER - parasites are less
likely to kill their hosts
In tropical forests, there are plants known as ant-plants. These plants provide nesting places and
nectar to ants and the presence of the ants protects the ant-plants from predation by herbivores.
This interaction between the ants and the ant-plants is - CORRECT ANSWER - mutualism
A fungus and algae grow together to produce what we call a lichen. When investigators separate
out the fungus from the algae and try to grow them in the same habitat but each alone, they all
die. What hypothesis most logically explains this phenomenon? - CORRECT ANSWER -
They both supply a necessary factor for the other to survive
The extermination of gray wolves from Yellowstone National Park caused dramatic declines in
the populations of many other species. When wolves were reintroduced to the park 70 years
later, many of these species rebounded. This is evidence that gray wolves are - CORRECT
ANSWER - a keystone species
The first species to live on new land, such as that formed from volcanic lava, are called -
CORRECT ANSWER - a pioneer species
