1 INTERRELATIONSHIPS Different ways species can get along, or not get along Predation + - Competition - - Parasitism + - Commensalism + o Mutualism + + + = benefit - = harmed 0 = unaffected e.g., +- means one gains, one loses

2 INTERRELATIONSHIPS Mutualism Which Type? Both the bee and the plant gain

3 INTERRELATIONSHIPS Competition Which Type? Both the bobcat and coyote lose when the other eats common food source

4 INTERRELATIONSHIPS Parasitism Which Type? The parasite gains, the host loses

5 INTERRELATIONSHIPS Predation Which Type?

6 INTERRELATIONSHIPS Commensalism Which Type? Snake gains home, rodent unaffected (hole abandoned long ago)

7 INTERRELATIONSHIPS: Review Mutualism Which Type? Both gain Coyote eats, seeds are dispersed

8 INTERRELATIONSHIPS: Review Competition Which Type? Both lose available soil moisture

9 INTERRELATIONSHIPS: Review Commensalism Which Type? Elf owl gains and woodpecker is unaffected Elf owl gains by using abandoned saguaro hole made by woodpecker
