  • Objectives 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.
  • Slide 3
  • Types of Adaptation Anything that helps an organism survive in its environment Anything that helps an organism survive in its environment Adaptations are inherited from their parents Adaptations are inherited from their parents It also refers to the ability of living things to adjust to different conditions within their environments. It also refers to the ability of living things to adjust to different conditions within their environments. Structural adaptation Structural adaptation Behavioral adaptations Behavioral adaptations Physiological adaptations Physiological adaptations I can identify an adaptation as structural, behavioral, or physiological.
  • Slide 4
  • Structural adaptations A structural adaptation involves some part of an organism's body. A structural adaptation involves some part of an organism's body. Teeth Teeth Body coverings Body coverings Shells Shells Quills Quills Scales Scales Camouflage Camouflage Mimicry Mimicry I can identify an adaptation as structural, behavioral, or physiological.
  • Slide 5
  • Example of Adaptation The shape of an animals teeth is related to its diet. The shape of an animals teeth is related to its diet. Herbivores, such as deer, have many molars for chewing tough grass and plants. Herbivores, such as deer, have many molars for chewing tough grass and plants. Carnivores, such as lions, have sharp canines to kill and tear meat. Carnivores, such as lions, have sharp canines to kill and tear meat. I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 6
  • Camouflage Camouflage allows an animal to blend into its environment. Camouflage allows an animal to blend into its environment. Makes it hard for enemies to single out individuals Makes it hard for enemies to single out individuals I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 7
  • Mimicry Mimicry allows one animal to look, sound, or act like another animal to fool predators into thinking it is poisonous or dangerous. Mimicry allows one animal to look, sound, or act like another animal to fool predators into thinking it is poisonous or dangerous. I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 8
  • Plant Adaptations Vascular-stems Vascular-stems Root systems Root systems Thorns Thorns Leave type Leave type Broad:absorb more sunlight Broad:absorb more sunlight Small needle-like: reduce water loss Small needle-like: reduce water loss Waxy: reduce water loss, protect from fire Waxy: reduce water loss, protect from fire Poisonous/toxins Poisonous/toxins I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 9
  • Behavioral adaptations Behavior adaptations include activities or behaviors that help an animal survive. Behavior adaptations include activities or behaviors that help an animal survive. 1. Innate 2. Learned 3. Survival 4. Seasonal I can identify an adaptation as structural, behavioral, or physiological.
  • Slide 10
  • Innate vs. Learned Innate Inherited through the genes Inherited through the genes Examples Examples Flying for bees, birds Swimming for fish Walking for humans Speaking for humans Learned Learned from experience or from observing other animals Learned from experience or from observing other animals Examples Examples Type of language spoken for humans Riding a bicycle I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 11
  • Survival Behavior 1. Finding food Predator-Prey adaptations Predator-Prey adaptations Predator-animals that eat other animals Predator-animals that eat other animals Prey-animal being eaten Prey-animal being eaten 2. Marking Territory Way that animals inform other animals that an area is occupied Way that animals inform other animals that an area is occupied 3. Defensive Action Protect resources, themselves, food, mates, offspring Protect resources, themselves, food, mates, offspring 4. Courtship Behaviors used to find a mate Behaviors used to find a mate 5. Parenting Depend on parents for survival Depend on parents for survival I can explain how an adaptation helps an organism survive in a particular environment.

  • Animal Defense Some animals use these methods of defense to protect themselves: Some animals use these methods of defense to protect themselves: Camouflage Camouflage Snake Snake Mimicry Mimicry Mexican Milk Snake Mexican Milk Snake Bright colors Bright colors Skunk and Poison Arrow Frog Skunk and Poison Arrow Frog Hair projections Hair projections Hedgehog quills Hedgehog quills Deer Antlers Deer Antlers I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 13
  • Seasonal Behavior Help organisms adapt to the environment Help organisms adapt to the environment 1. Migration 2. Hibernation 3. Estivation 4. Biological Clock I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 14
  • Migration Animals migrate for different reasons. Animals migrate for different reasons. better climate better climate better food better food safe place to live safe place to live safe place to raise young safe place to raise young go back to the place they were born. go back to the place they were born. Adaptation that involves an animal or group of animals moving from one region to another and then back again. Adaptation that involves an animal or group of animals moving from one region to another and then back again. I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 15
  • Hibernation Period of inactivity in which animals body temp., heart rate, and breathing rate slow down to conserve energy. Period of inactivity in which animals body temp., heart rate, and breathing rate slow down to conserve energy. Bats, woodchucks & bears. Bats, woodchucks & bears. I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 16
  • Estivation Period of inactivity in the summer Period of inactivity in the summer hot, dry places hot, dry places Snakes, lizards, frogs, toads Snakes, lizards, frogs, toads I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 17
  • Biological Clock Internal control of animals natural cycle Internal control of animals natural cycle I can explain how an adaptation helps an organism survive in a particular environment.
  • Slide 18
  • Physiological Adaptations Behaviors controlled by the brain Behaviors controlled by the brain Reflexes Reflexes Blinking Blinking Pain Pain Swallowing Swallowing Tolerance to a certain poison Tolerance to a certain poison Logical thinking Logical thinking I can identify an adaptation as structural, behavioral, or physiological.
