Across
  1. 4. Behaviors that help animals migrate and home safely. Innate behaviors that can be refined (made better) with repeated experience.
  2. 7. Any trait that results in an organism having a greater chance of surviving to an age where it can reproduce and pass on its successful trait.
  3. 10. The speed of the movement is related to intensity of stimulus. Speed increases when the animal is in an unfavorable environment, speed decreases when the animal is in a favorable environment.
  4. 12. movement of an animal away from the direction of gravity
  5. 15. movement of an animal toward light
  6. 18. Non directional movement of an animal in response to a stimulus. They end up moving toward or away from the stimulus by CHANCE.
  7. 19. movement of an animal away from light
Down
  1. 1. movement of an animal away from a chemical stimulus
  2. 2. The rate of turning is related to intensity of stimulus. Turning increases when the animal is in an unfavorable environment, turning rate decreases when the animal is in a favorable environment.
  3. 3. movement of an animal with the direction of gravity
  4. 5. the use of the Earth's magnetic field to navigate. Innate and common in birds. Does not require sight.
  5. 6. Use of familiar landmarks to check orientation along a migration or homing route. Learnt behavior only NOT innate.
  6. 8. movement of an animal toward a chemical stimulus
  7. 9. Regular mass movement of animals of the same species to a different environment, usually seasonal, to a predetermined location.
  8. 11. Behaviors present from birth, they are controlled by genes inherited from parents.
  9. 13. Behavior that can be changed or improved with repeated experience.
  10. 14. Ability of an animal to repeatedly return to its home location after travelling away from it to get resources eg. food.
  11. 16. the use of the sun for orientation during navigation or homing. Can only occur during the day and when the weather is good.
  12. 17. Directional movement of an animal toward or away from a stimulus.
