BIOL 1104 Final Exam Questions with
Correct Answers
Population - CORRECT ANSWER -all interbreeding or potentially
interbreeding individuals of one species in a given
area
Community - CORRECT ANSWER -- all interacting populations in an
ecosystem (more than one species)
Ecology - CORRECT ANSWER -study of interactions between organisms
and within their environment
Biotic - CORRECT ANSWER -living components
Abiotic - CORRECT ANSWER -physical/chemical components
Principle of Competitive Exclusion - CORRECT ANSWER -
the concept that no two species can simultaneously and continuously occupy the same ecologi
cal niche.
Parasitism - CORRECT ANSWER -harming hosts but not necessarily killing;
positive for parasite but negative for host
Aggressive mimicry - CORRECT ANSWER -
the evolution of a predatory organism to resemble a harmless animal or a part of the environm
ent, thus gaining access to prey.
, climax community - CORRECT ANSWER -
a diverse and relatively stable community that forms the endpoint of succession.
coevolution - CORRECT ANSWER -
the evolution of adaptations in two species due to their extensive interactions with one anothe
r, such that each species acts as a major force of natural selection on the other.
community - CORRECT ANSWER -all the interacting populations within an ecosystem.
competition - CORRECT ANSWER -
interaction among individuals who attempt to utilize a resource (for example, food or space) th
at is limited relative to the demand for that resource.
ecological niche - CORRECT ANSWER -
the role of a particular species within an ecosystem, including all aspects of its interaction with
the living and nonliving environments.
interspecific competition - CORRECT ANSWER -
competition among individuals of different species.
intraspecific competition - CORRECT ANSWER -
competition among individuals of the same species.
keystone species - CORRECT ANSWER -
a species whose influence on community structure is greater than its abundance would sugges
t.
mimicry - CORRECT ANSWER -
the situation in which a species has evolved to resemble something else, typically another type
of organism.
