Answer
  • being able to exploit their own environmental niches
  • being able to find food quickly
  • specific behavioural, physiological, or anatomical changes to suit their needs/environment
  • how organisms have evolved to suit their surroundings

Question 5

Question
Behavioural adaptations are [blank_start]actions[blank_end] that help organisms to [blank_start]survive and reproduce[blank_end]. Anatomical adaptations are the [blank_start]structures[blank_end] we see when we [blank_start]dissect or observe[blank_end] an organism. Physiological adaptations relate to the [blank_start]internal workings[blank_end] of organisms that help them survive and/or reproduce.
