Biotic Relationships:Community Interactions
Biotic Relationships Competition Predation Symbiosis
Competition Examples:Organisms attempt to use a resource in the same place at the same time Examples: Water Nutrients Light Food space
Predation One organisms captures and feeds on anotherPredator is the killer/eater Prey is the food
Symbiosis Any relationship in which two species live closely togetherThree main classes: Mutualism Commensalism Parasitism
Mutualism Both species benefit Example: flower and bee
Commensalism One benefits, the other is neither benefited nor harmedExample: barnacles and whale Barnacle filter feeds
Parasitism One benefits, the other is harmedParasite lives on or in the host, and obtains some/all of its nutrients from host Examples: tapeworms, fleas, ticks, lice

Shaping an Ecosystem. Biotic and Abiotic Factors Ecosystems are influences by living and non living Biotic factors: all biological factors in an ecosystem.
Relationships in the Ecosystem. What are the types of relationships? 1)Predator / Prey 2)Competition 3)Symbiosis A) commensalism B) mutualism C) parasitism.
Lesson 3-How Do Organisms Interact? - Observe how organisms help each other - Describe how organisms compete within an ecosystem - Explain symbiotic relationships.
