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