  Structural change which gives an organism a greater chance of survival in its habitat.
• What is behavioural adaptation?

  Way an organism reacts to its environment which aids its survival.
• Biodiversity and endangered animals are protected by:

  2. Sites of Special Scientific Interests (SSSI)
  3. Captive breeding programs
  4. National parks
