Presentation transcript:

L3: Ecological Relationships Learning Objectives: Describe different ecological relationships between organisms. Explain the symbiotic relationships of mutualism, parasitism, and commensalism.

Relationships Competition Predation Symbiosis Mutualism Commensalism Parasitism

Competition – when organisms both rely on the same resource (example: food) Predation – when one organism eats another Symbiosis – close, unique relationship between two organisms Mutualism – symbiotic relationship when both organisms benefit Commensalism – symbiotic relationship when one organism benefits and the other is not harmed Parasitism – symbiotic relationship when one organism benefits while harming the other

Activity: Identify the type of ecological relationship We are going to watch a series of videos. Identify which type of ecological relationship is being shown.
