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