Biology 1407 Exam questions and
answers graded A+
trophic - ANS✅✅feeding
symbiosis - ANS✅✅one species lives in or on another species, affect can be positive or negative
predation - ANS✅✅one species' individual kills and eats another species' individual
carnivory - ANS✅✅predator and prey are both animals
herbivory - ANS✅✅predator is an animal and the prey is a plant
parasitism - ANS✅✅a parasite lives in or on its host feeding off certain tissues without necesarily
killing them
competition - ANS✅✅two or more species overlap in the use of limiting resources, negatively
affects their growth, reproduction, and/or survival
positive interactions - ANS✅✅at least one species benefits from the interaction
mutualism - ANS✅✅both species benefit
commensalism - ANS✅✅one benefits, the other is unaffected
ammensalism - ANS✅✅one is unaffected, the other is harmed
batesian mimicry - ANS✅✅nontoxic species mimics a toxic species
mullerian mimicry - ANS✅✅two or more species converge on a common color pattern
, microparasites - ANS✅✅smaler than their hosts, many are pathogens, viruses, bacteria and
protists
macroparasites - ANS✅✅rarely cause disease symptoms
endoparasites - ANS✅✅spend at least part of their life cycle inside the host
ex: tapeworms
ectoparasites - ANS✅✅live outside the host body
ex: leeches
keystone species - ANS✅✅a species that controls the effects of predation on a community
niche - ANS✅✅the physical and biological conditions required for growth, reproduction, and
survival
fundamental niche - ANS✅✅niche defined by a species' physiological capabilities
realized niche - ANS✅✅niche defined by a species' interaction with other species
competitive exclusion - ANS✅✅one species prevents another from using essential resources
competitive coexistence - ANS✅✅ability to coexist despite sharing limiting resources
resource partitioning - ANS✅✅sharing of limiting resources by using them in different ways
character displacement - ANS✅✅individuals in a species that evolve different behaviors or
morphologies if competing with another species
frugivores - ANS✅✅animals that eat fruit and spread their seeds
guild - ANS✅✅group of species that use similar resources
