Species Interactions. When organisms live together in a community, they interact constantly. These interactions help shape the ecosystem they live in.

Ecological Relationships. Competition and Predation Competition – occurs when organisms of the same or different species attempt to use an ecological.

1.2 Interdependence No species can live by itself,each species is dependent on another 3 Symbiotic Relationships Commensalism: one organism benefits but the other does not. Eg. baracles Mutualism: both organisms benefit Eg. sucker fish and shark Parasitism: one organism benefits and the other is harmed. Eg. tapeworm

Clownfish & Sea Anemone Flowers & Pollinators Tapeworm

Interdependence cont’d Niches: the role of an organism within its environment. Includes what the organism eats, habitat, nesting site, predators, etc. Interspecies Competition: two or more species need the same resources Resource Partitioning: the species divide up the resources equally to ensure survival. Eg. warblers
