BIOL 1104 Final Exam Questions with
Correct Answers 2025-2026
Population COORRECT ANSWER all interbreeding or potentially
interbreeding individuals of one species in a given
area
Community COORRECT ANSWER - all interacting populations in an
ecosystem (more than one species)
Ecology COORRECT ANSWER study of interactions between
organisms and within their environment
Biotic COORRECT ANSWER living components
Abiotic COORRECT ANSWER physical/chemical components
Principle of Competitive Exclusion COORRECT ANSWER
the concept that no two species can simultaneously and continuously occupy the same ecologi
cal niche.
Parasitism COORRECT ANSWER harming hosts but not necessarily
killing; positive for parasite but negative for host
Aggressive mimicry COORRECT 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 COORRECT ANSWER
a diverse and relatively stable community that forms the endpoint of succession.
coevolution COORRECT ANSWER
the evolution of adaptations in two species due to their extensive interactions with one anothe

community COORRECT ANSWER all the interacting populations within an ecosystem.
competition COORRECT 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 COORRECT ANSWER
the role of a particular species within an ecosystem, including all aspects of its interaction with
the living and nonliving environments.
interspecific competition COORRECT ANSWER
competition among individuals of different species.
intraspecific competition COORRECT ANSWER
competition among individuals of the same species.
keystone species COORRECT ANSWER
a species whose influence on community structure is greater than its abundance would sugges
t.
mimicry COORRECT ANSWER
the situation in which a species has evolved to resemble something else, typically another type
of organism.
