1 20.1: SPECIES INTERACTIONS (SYMBIOSIS)

2 Symbiosis- close ecological relationship between two or more organisms of different species that live in direct contact

3 1. MUTUALISM ( +/+) Both benefit EX. Clown fish get shelter and anemone gets free cleaning. http://www.pbslearningmedia.org/ asset/nat08_vid_travcom/ http://www.pbslearningmedia.org/ asset/nat08_vid_travcom/

4 2. COMMENSALISM (+/0) One benefits and one is neither helped nor harmed EX. Barnacles on Grey Whale

5 3. PARASITISM (+/-) …. But not instantly killed Parasite: small and lives on or in the host organism Usually does not result in immediate death

6 3. PARASITISM (+/-) …. But not instantly killed Parasite: small and lives on or in the host organism Usually does not result in immediate death Weaken the host Evolutionary adaptation keep the host healthy enough to allow parasite reproduction EX. intestinal worms / humans
