Goal: I will be able to Compare and Contrast ways
organisms interact

Symbiosis
 Relationship between species living in close
association with each other
Adaptations
 An anatomical,
physiological, or
behavioral change that
improves a population’s
ability to survive
Predation
 Relationship where the predator hunts and kills
the prey for food
 Determines relationships in food webs and
regulates population size
 Nature favors organisms that have adaptations that
improve likelihood of survival
 Ex: Speed, good vision/hearing, camouflage, defense
mechanisms
Parasitism
 Relationship where one species benefits and the other
is harmed
 A parasite does not necessarily kill its host
 Ectoparasites are external

Ex: Tick, Flea, Lice, Mosquito, Fungus, Leaches
 Endoparasites are internal

Tapeworms, Bacteria, Heartworm
Competition
 Relationship where limited resources are competed for
 Intraspecific (with in a species) vs. Interspecific
(between species)
 Competitive Exclusion Principle: species less suited to
compete will adapt/die
Mutualism
 Relationship were both species benefit
 Species cooperate for survival
 Ex: Animals clean bodies/mouths of other animals.
Pollination by bees of flowers (monarch butterfly and
milkweed). Sea anemone and clownfish
Commensalism
 Relationship where one species benefits and other in
neither helped nor harmed
 Ex: Birds eat insects forced out of hiding by livestock:
Remora shark/barnacles ride larger animals.
Orchids/moss on trees. Jackels/Hyena trailing kill of
tigers/lions
