A. An Organism’s Niche
• 1. A niche can be a range of conditions in which a species can survive.
B. Competition
• 1. Relationship in which different individuals or populations attempt to use the same limited resource.
C. Predation
• 1. When a predator feeds upon its prey.
C. Predation

D. Parasitism
• 3. The host is the organism a parasite gets it nourishment (food) from.
E. Mutualism
• 1. Relationship in which 2 species benefit each other for survival.
F. Commensalism
• 1. Relationship in which one organism benefits and another is not harmed or helped (neutral).
G. Symbiosis and Coevolution
• 1. Relationship in which 2 species live in close association.
G. Symbiosis and Coevolution
• 2. Over time, these relationships may coevolve their adaptations in response to each other.
