What are the Interactions among organism?: àThere are four types of interactions: 1.)Adaptations: Behaviors and physical characteristics that allow organisms to survive in their environment. 1 Physical Adaptations: Body structures which help an animal survive in it's environment. ex.) An elephants trunk helps it eat and drink upright so it keep watch for danger like predators. 2 Behavioral Adaptations Animals actions which allow them to respond to life needs. ex.) Defending itself and offspring Gathering and storing food Finding shelter Hibernating Migrating 3 ØPhysical or behavioral adaptations happen through a process called: Natural Selection ________________________ A process in which adaptations help an organism to survive better in an environment and have more babies. Those babies than inherit those characteristics and continue to pass them on to future generations. 4 Physical or Behavioral? 5 2.) Symbiosis: A close relationship between two species that benefits at least one of the species. 6 Mutualism: A relationship where both species benefit Example: ____________________________________________________ Sea Anemone and Clown fish: Anemone protects the clown fish because it stings while the clown fish draws in food for the anemone to eat. 7 Commensalism: Relationship where one species benefits and the other species is neither helped nor harmed. Example: _____________________________________ o Hitchhiker insect; Small insect gets a free ride, fly doesn’t notice 8 Parasitism: Relationship which involved one organism living on or inside another organism and harming it. Example: _________________________________________ Humans and mosquitoes, they LOVE us for our blood we HATE them. • The organism that benefits is called the parasite, while the organism that is harmed is called the host. 9 3.) Competition: The struggle between organism to survive as they attempt to use the same limited resource. Land, Ladies, Leader, Lunch Limited Resources: (The 4 L’s) __________________________________________________ o Example: ____________________________________________________________ Two males fighting over territory, or wolves fighting to be the alpha 10 4.) Predation: One organism kills another organism for food Ex.) A cheetah killing a gazelle for food 11 Date T I L 2 full sentences about what you learned today 12 Adaptation Ideas Eyes on stalks Claws Big Ears Numerous arms/legs Speech Color Change Beak Regenerated body parts Form Change Night Vision Climbing Digging Flying Colored Fur Slimy Skin Hoofs Sharp Teeth Venom Long Hair Feathers Flippers Suction Cups Speed Fire Breathing Spikes Multiple Heads Sounds 13
