Predator/Prey An organism KILLS and EATS all or part of another organism.

Competition Organisms compete for resources or same goal that two cannot attain –Ex.) Plants in the Rainforest competing for light –Two birds competing for a mate

Symbiosis Close, long-term relationship(s) between different species within an eco-system. 3 Major types- Mutualism, Commensalism, and Parasitism

Mutualism This is a win- win relationship Both organisms benefit from each other

Commensalism This is a win-?? (no one cares) relationship One organism benefits, the other one doesn’t care – it isn’t helped or harmed. 

Parasitism This is a win-lose relationship One organism benefits, the other is harmed  tick flea
