In our region, the habitat of a packrat ranges from the lower mountains into the creosote desert, preferably bajadas and rocky slopes.
True or False
True
Generally generations of packrats occupy the same site for thousands of years.
True or False
True
The study of packrat middens can reveal past climates.
True or False
True
Packrat midden contents reveal changes in plant and animal communities.
True or False
True
Through studying packrat middens, scientists have discovered that approximately 12,000 years ago this area was not desert.
True or False
True
Moths are attracted to flowers that: open at night, long floral tube, white or pale color, delicate substance, sickly-sweet fragrance.
True or False
True
Two species can occupy the exact same niche within the same place at the same time, indefinitely.
True or False
False
Identify the following phenomena as examples of: (a term may apply more than once, or not at all)
a. Intraspecific competition.
b. Interspecific competition.
c. Mutualism.
d. Parasitism.
e. Commensalisms.
f. Predation
____ A coyote eats a rabbit.
____ Two bighorn rams butt heads for the opportunity to mate with a ewe.
____ A bee visits a saguaro flower. Then it flies to another saguaro, and inadvertently transfers pollen from the flower of the first saguaro to the stigma of a flower on the second saguaro.
____ Lice feed on blood from your scalp.
____ An oak tree’s canopy shades a pine tree, which dies from insufficient light.
____ A toad finds moisture and coolness deep in a squirrel’s burrow. The squirrel is scarcely aware of the toad’s presence.
____ A hummingbird chases a hawkmoth away from a patch of flowers, defending the nectar source for its exclusive use.
___f___ A coyote eats a rabbit. (predation)
___a___ Two bighorn rams butt heads for the opportunity to mate with a ewe. (Intraspecific competition)
___c___ A bee visits a saguaro flower. Then it flies to another saguaro, and inadvertently transfers pollen from the flower of the first saguaro to the stigma of a flower on the second saguaro. (Mutualism)
___d___ Lice feed on blood from your scalp. (parasitism)
___b___ An oak tree’s canopy shades a pine tree, which dies from insufficient light. (Interspecific competition)
___e___ A toad finds moisture and coolness deep in a squirrel’s burrow. The squirrel is scarcely aware of the toad’s presence. (Commensualism)
___b___ A hummingbird chases a hawkmoth away from a patch of flowers, defending the nectar source for its exclusive use. (Interspecific Competition)
Match the correct definition to the term.
____ Symbiosis
____ Mutualism
____ Commensalism
____ Parasitism
a. One organism lives on or in (and usually feeds upon) a second organism that is much larger than itself and remain associated with them for long periods of time. Broomrape, sandfood, mistletoe.
b. One partner benefits from the relationship and the other partner is not harmed, nor does it significantly benefit. Gila woodpecker and saguaro.
c. Both partners derive benefit from the relationship. * Old definition meant an obligatory relationship.
d. The living together of two or more species in a prolonged and intimate ecological relationship. A close ecological relationship between organisms of different species which does not necessarily benefit both species.
___d___ Symbiosis
___c___ Mutualism
___b___ Commensalism
___a___ Parasitism
