Community Interactions
Competition PredationSymbiosis
Competition Organisms of the
same or different species attempt to use the same ecological resource (food, water, space) in the same place at the same time
Competition
Two different butterfly species feeding on the same flowers
Two organisms want the same thing
Predation Interaction in which
one organism

Rabbit and Coyote

Ultimate Predator? Why is man
sometimes called the “Ultimate Predator”?
SymbiosisAny relationship in which two
species live closely together is called symbiosis (“living together”)
MutualismCommensalismParasitism
Mutualism Both organisms
benefit
Examples: Flowers and insects Ants and aphids- ants feed off the excrement (honeydew)
of aphids, and ants protect aphids
Mutualism Lichen
Algae and fungus living together
Commensalism One member of the
association benefits and the other is neither helped nor harmed.
Examples:Spanish moss
Commensalism Whales &
Barnacles
Barnacles are "filter feeders“. Many filter feeders compete for
space on the ocean floor. Barnacles avoid this
competition by attaching themselves to whales.
Commensalism
Epiphytes“air plants”
Biology, Prentice Hall
Parasitism One benefits; one harmed
Examples: tapeworms inside mammals; fleas, ticks, and lice on mammals
Parasitism
Ticks
The parasite obtains all or part of its nutritional needs from the other organism, the host.
Blacklegged Tick: An adult female blacklegged tick, engorged after a
blood meal, rests on a leaf.
