Goal: I will be able to Compare and Contrast ways organisms interact Foldable Instructions Create Foldable with 6 flaps 2. Label the flaps (in this order) 1. Symbiosis and Adaptations (No picture necessary) Predation Parasitism Competition Mutualism Commensalism 3. Draw and Color illustration showing the interaction 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 Shark Video Clip 1 Clip 2 Clip 3
