BEHAVIOURS FOR SURVIVAL

  1. 1. AdaptationsAdaptations
  2. 2. ObjectivesObjectives  SPI 0807.5.2 Analyze structural, behavioral, and physiological adaptations to predict which populations are likely to survive in a particular environment  SPI 0807.5.3 Analyze data on levels of variation within a population to make predictions about survival under particular environmental conditions. I can:  Identify an adaptation as structural, behavioral, or physiological.  Explain how an adaptation helps an organism survive in a particular environment.
  3. 3. Types of AdaptationTypes of Adaptation  Anything that helps an organism survive inAnything that helps an organism survive in its environmentits environment  Adaptations are inherited from their parentsAdaptations are inherited from their parents  It also refers to the ability of living things toIt also refers to the ability of living things to adjust to different conditions within theiradjust to different conditions within their environments.environments.  Structural adaptationStructural adaptation  Behavioral adaptationsBehavioral adaptations  Physiological adaptationsPhysiological adaptations I can identify an adaptation as structural, behavioral, or physiological.

Structural adaptationsStructural adaptations  AA structural adaptationstructural adaptation involvesinvolves some part of an organism's body.some part of an organism's body.  TeethTeeth  Body coveringsBody coverings  ShellsShells  QuillsQuills  ScalesScales  CamouflageCamouflage  MimicryMimicry I can identify an adaptation as structural, behavioral, or physiological.

Example of AdaptationExample of Adaptation  The shape of anThe shape of an animal’s teeth isanimal’s teeth is related to its diet.related to its diet.  Herbivores, such asHerbivores, such as deer, have manydeer, have many molars for chewingmolars for chewing tough grass andtough grass and plants.plants.  Carnivores, such asCarnivores, such as lions, have sharplions, have sharp canines to kill and tearcanines to kill and tear meat.meat. I can explain how an adaptation helps an organism survive in a particular environment.
