BIOLOGY 1407 EXAM 2 REVIEW QUESTIONS AND
ANSWERS
/. trophic - Answer-✅feeding
/.symbiosis - Answer-✅one species lives in or on another species, affect can be
positive or negative
/.predation - Answer-✅one species' individual kills and eats another species' individual
/.carnivory - Answer-✅predator and prey are both animals
/.herbivory - Answer-✅predator is an animal and the prey is a plant
/.parasitism - Answer-✅a parasite lives in or on its host feeding off certain tissues
without necesarily killing them
/.competition - Answer-✅two or more species overlap in the use of limiting resources,
negatively affects their growth, reproduction, and/or survival
/.positive interactions - Answer-✅at least one species benefits from the interaction
/.mutualism - Answer-✅both species benefit
/.commensalism - Answer-✅one benefits, the other is unaffected
/.ammensalism - Answer-✅one is unaffected, the other is harmed
/.batesian mimicry - Answer-✅nontoxic species mimics a toxic species
/.mullerian mimicry - Answer-✅two or more species converge on a common color
pattern
/.microparasites - Answer-✅smaler than their hosts, many are pathogens, viruses,
bacteria and protists
/.macroparasites - Answer-✅rarely cause disease symptoms
/.endoparasites - Answer-✅spend at least part of their life cycle inside the host
, ex: tapeworms

community
/.niche - Answer-✅the physical and biological conditions required for growth,
reproduction, and survival
/.fundamental niche - Answer-✅niche defined by a species' physiological capabilities
/.realized niche - Answer-✅niche defined by a species' interaction with other species
/.competitive exclusion - Answer-✅one species prevents another from using essential
resources
/.competitive coexistence - Answer-✅ability to coexist despite sharing limiting resources

behaviors or morphologies if competing with another species
/.frugivores - Answer-✅animals that eat fruit and spread their seeds
/.guild - Answer-✅group of species that use similar resources
/.functional group - Answer-✅species that function in similar ways but may not use
similar resources

such as competition and positive interactions
/.species composition - Answer-✅kinds of species
/.community structure - Answer-✅patterns of species diversity and composition at the
community or local scale
