Survival Relationships• Predator-prey – Predators seek out and eat

other organisms• Competition—two species or organisms

have niche overlap; they share food, water, shelter or mates; one will win and other must adapt through natural selection

• Symbiosis – A relationship in which there is a close and permanent association between organisms of different species.

Mutualism• Symbiotic

relationship in which both species benefit.

Parasitism• A symbiotic

relationship in which one organism benefits at the expense of the other.

Page 4: Survival Relationships Predator-prey – Predators seek out and eat other organisms Competition—two species or organisms have niche overlap; they share food,

Commensalism• A symbiotic

relationship where one species benefits and the other is neither harmed or helped. (many are now seen as undefined mutualism)

Survival Relationships

• Mutualism – is a symbiotic relationship in which both species benefit. (+/+)

• Commensalism – is a symbiotic relationship in which one species benefits and the other is neither harmed nor benefited. (+/0)

• Parasitism – is a symbiotic relationship in which one species benefits and the other is harmed (+/-)
