SYMBIOTIC RELATIONSHIPS: Parasitism
Symbol: +/-
Effect on organisms: one organisms benefits (the parasite), whilst another organisms is harmed (the host)
Example: tapeworm living in intestines of pig, causing illness and death
SYMBIOTIC RELATIONSHIP: Mutualism
Symbol: +/+
Effect on organisms: both organisms benefits
Examples: figs rely on fly wasps to pollinate the flowers and provide habitat for wasps larvae
SYMBIOTIC RELATIONSHIP: Commensalism
Symbol: +/0
Effect on organisms: one organism benefits the other is unharmed
Example: whales provide habitat for barnacles which does not harm the whale
