Community Interactions EQ: How do the three types of symbiosis differ?

Types of Interactions Competition Predation Symbiosis  Mutualism  Commensalism  Parasitism

Competition (-/-) Organisms of the same or different species attempt to use the same ecological resource in the same place at the same time Bison Elk Herd Moose

Competition Interspecific competition: Competition between members of different species Intraspecific competition: Competition among members of the same species Blue Butterfly Tiger Swallowtail butterfly

Competitive exclusion principle: No two species can occupy exactly the same niche in exactly the same habitat at exactly the same time. One will always exclude the other

Predation (+/-) Herbivory: Type of predation Interaction in which an herbivore feeds on producers. predator prey Falcon Ground Squirrel Interaction in which one organism captures and feeds on another organism

Predation Keystone species: a single species that is vital to the ecosystem stability. Ex. Otters/kelp/sea urchins

Predation Rabbit and Coyote rabbit coyote Arctic Hare Coyote

Symbiosis Any relationship in which two species live closely together is called symbiosis (“living together”) Mutualism Commensalism Parasitism

Mutualism (+/+) Both organisms benefit o Examples: o Flowers and insects o Ants and aphids Bee on Purple Flower Ant and Aphid

Mutualism (+/+) Lichen Algae and fungus living together Lichen

Commensalism (+/0) One member of the association benefits and the other is neither helped nor harmed. Spanish Moss

Commensalism (+/0) Whales & Barnacles Barnacles on Whale

Commensalism (+/0) Epiphytes “air plants” Epiphyte Epiphyte in Tree

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. Before After Black Legged Tick

Parasitism (+/-) One benefits; one harmed Examples: tapeworms inside mammals; fleas, ticks, and lice on mammals Female Head Lice

Parasitism (+/-) Mistletoe More than just a “kissing catalyst” Mistletoe
