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

INTERRELATIONSHIPSMutualism

Which Type?

Both the bee and the plant gain

INTERRELATIONSHIPSCompetition

Which Type?

Both the bobcat and coyote lose when the other eats common food source

INTERRELATIONSHIPSParasitism

Which Type?

The parasite gains, the host loses

INTERRELATIONSHIPSCommensalism

Which Type?

Snake gains home, rodent unaffected (hole abandoned long ago)
