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
captures and feeds on another organism
predator
prey

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.

Parasitism One benefits; one harmed
Examples: tapeworms inside mammals; fleas, ticks, and lice on mammals
![Page 15: Community Interactions Competition Predation Symbiosis](https://reader036.vdocument.in/reader036/viewer/2022081507/5a4d1b0a7f8b9ab05998a24c/html5/thumbnails/15.jpg)
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.
