Presentation transcript:

Learning Objectives Identify the interactions that occur within communities

Community Interactions Community interactions, such as competition, predation and symbiosis can have a great affect on the ecosystem

Competition Competition - Organisms of the same or different species attempt to use an ecological resource in the same place at the same time

Predation Predation - one organism captures and feeds on another organism

YouTube Community Ecology

Symbiosis Symbiosis - Any relationship in which two species live closely together

Mutualism Mutualism - both species benefit from the relationship.

Commensalism Commensalism - One member benefits and the other is neither helped or harmed

Parasitism Parasitism - One organism lives on or inside another organism and harms it

Niche Niche is the range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions.
