Exam-BIOL 1108 - Exam 4 with Complete Solutions
Niche CORRECT ANS-Multidimensional habitat that allows species to practice its way of
life.
Profession - ecological role played by a species in its community.
Resource partitioning CORRECT ANS-Species whose niches overlap may diverge to
minimize the overlap.
Fundamental niche CORRECT ANS-Full range of climate conditions and food resources that
permits the individual in a species to live.
Realized niche CORRECT ANS-The actual range of habitats occupied by a species.
Interspecific vs intraspecific competition CORRECT ANS-Inter - with other species
Intra - with own species
Symbioses CORRECT ANS-Close interactions with species
, Exam-BIOL 1108 - Exam 4 with Complete Solutions
Mutualism CORRECT ANS-Mutually beneficial interactions
Antagonism CORRECT ANS-At least one participant loses more than it gains.
Direct interactions CORRECT ANS-Species physically interact
Indirect interactions CORRECT ANS-Species influence one another through competition for
a shared resource
Competition CORRECT ANS-Interaction in which the use of a mutually needed resource by
one individual lowers the availability of the resource for another individual.
Both sides lose energy they would not lose in the absence of the other.
Competition promotes niche divergence CORRECT ANS-One species will either become
extinct in that place or change its resource use.

Competitive exclusion CORRECT ANS-One species is prevented from occupying a particular
habitat or niche.
Mutualism may cause increasing interdependence CORRECT ANS-Reciprocal adaptations in
both participants...descendants of each side will also be associated with each other.
Obligate mutualism CORRECT ANS-When one or both sides of a mutualism cannot survive
without the other.
Facultative mutualism CORRECT ANS-One or more of the participants can survive without
the other.
Commensalism CORRECT ANS-One partner benefits without an apparent effect on the
other.
Amensalism CORRECT ANS-One partner is harmed with no apparent effect on the other.
