recycled
Predation/Parasitism |- |CORRECT |ANSWER✔✔-Predator |benefits, |prey |suffers
Parasitism |- |CORRECT |ANSWER✔✔-(+,-) |One |organism |(parasite) |benefits, |while |the |other |
(host) |is |harmed
Herbivory |- |CORRECT |ANSWER✔✔-(+/-) |interaction |in |which |an |organism |eats |parts |of |a |plant |
or |alga
Competition |- |CORRECT |ANSWER✔✔-(-/-) |the |struggle |between |organisms |to |survive |in |a |
habitat |with |limited |resources
Mutualism |- |CORRECT |ANSWER✔✔-(+/+) |Both |organisms |benefit |from |interaction/relationship
Commensalism |- |CORRECT |ANSWER✔✔-(+/o) |One |organism |benefits |and |the |other |is |
unaffected
Habitat |- |CORRECT |ANSWER✔✔-Place/physical |setting
Niche |- |CORRECT |ANSWER✔✔-Physical |organism |where |an |organism |lives
-substrate |(soil,water)
-other |species |needed |for |persistence
