  • Adaptations are features that enable organisms to survive in their natural environments.
  • These adaptations allow organisms to outcompete others and can lead to evolution.
  • The concept of evolution related to adaptations is covered elsewhere in the course.
  • Students need to understand and explain the categories of adaptations in exams.
  • Categories of adaptations include structural, behavioral, and functional adaptations.
  • Structural adaptations are physical features like sharp claws in lynxes, which help in hunting and climbing.
  • Examples of structural adaptations in plants include sunken stomata in marram grass to reduce water loss and spines in cacti for protection.
  • Behavioral adaptations include mating rituals like peacocks displaying feathers and tool use by chimpanzees for feeding.
  • Functional adaptations involve natural body functions such as secretion of poison in cane toads for defense and hibernation in hedgehogs to conserve energy during winter.
  • Students need to be familiar with these adaptation types but specific examples are not required for the exam.
