BIOLOGY 1407 EXAM 2 REVIEW
QUESTIONS AND ANSWERS
trophic - Correct Answers -feeding
symbiosis - Correct Answers -one species lives in or on another species, affect can be
positive or negative
predation - Correct Answers -one species' individual kills and eats another species'
individual
carnivory - Correct Answers -predator and prey are both animals
herbivory - Correct Answers -predator is an animal and the prey is a plant
parasitism - Correct Answers -a parasite lives in or on its host feeding off certain tissues
without necesarily killing them
competition - Correct Answers -two or more species overlap in the use of limiting
resources, negatively affects their growth, reproduction, and/or survival
positive interactions - Correct Answers -at least one species benefits from the
interaction
mutualism - Correct Answers -both species benefit
commensalism - Correct Answers -one benefits, the other is unaffected
ammensalism - Correct Answers -one is unaffected, the other is harmed
batesian mimicry - Correct Answers -nontoxic species mimics a toxic species
mullerian mimicry - Correct Answers -two or more species converge on a common color
pattern
microparasites - Correct Answers -smaler than their hosts, many are pathogens,
viruses, bacteria and protists
macroparasites - Correct Answers -rarely cause disease symptoms
, endoparasites - Correct Answers -spend at least part of their life cycle inside the host
ex: tapeworms
ectoparasites - Correct Answers -live outside the host body
ex: leeches
keystone species - Correct Answers -a species that controls the effects of predation on
a community
niche - Correct Answers -the physical and biological conditions required for growth,
reproduction, and survival
fundamental niche - Correct Answers -niche defined by a species' physiological
capabilities
realized niche - Correct Answers -niche defined by a species' interaction with other
species
competitive exclusion - Correct Answers -one species prevents another from using
essential resources
competitive coexistence - Correct Answers -ability to coexist despite sharing limiting
resources
resource partitioning - Correct Answers -sharing of limiting resources by using them in
different ways
character displacement - Correct Answers -individuals in a species that evolve different
behaviors or morphologies if competing with another species
frugivores - Correct Answers -animals that eat fruit and spread their seeds
guild - Correct Answers -group of species that use similar resources
functional group - Correct Answers -species that function in similar ways but may not
use similar resources
food webs - Correct Answers -representations of trophic or energetic connections
among species
interaction webs - Correct Answers -food web depictions that include nontrophic
interactions such as competition and positive interactions
species composition - Correct Answers -kinds of species
