Presentation transcript:

Ecological Relationship: relationship between organisms in an ecosystem

Mutualism: A symbiotic relationship where both species benefit Keywords: Equal benefit Example: Humans and Bacteria

Commensalism: A relationship that benefits one organism and neither hurts nor helps the other Keywords: one benefits, other unaffected Example: Whales and Barnacles

Parasitism: one organism feeds on the tissues or body fluids of another organism Keywords: one hurts the other Example: Lamprey and Fishes

Predation: One organism actively hunts another organism Keywords: one hunts another Example: Boa and Gazelle

Scavenger: Organisms that feed dead plants or animals Keywords: eats dead material Example: The Vulture

Competition: When two or more organisms compete for the same resource Keywords: both compete Example: Coyotes vs. red foxes; compete for the same food source (rodents and birds)
