Homing and Navigation

Which of these is an example of how a pigeon uses an innate behavior to navigate?

• Using magnetoreceptors to fly North

• Using magnetoreceptors to recognise the local magnetic field

• Using chemoreceptors (nose) to recognise local smells

• Using photoreceptors (eyes) to recognise local landmarks

Which of these is an example of a bee using an innate navigation technique?

• Waggle dancing to communicate where a flower is

• Using an internal sense of time and photoreceptors (eyes) to detect where the sun is in the sky and use it as a compass.

• Recognising local landmarks near its hive

• Using chemoreceptors to recognise familiar smells

Which of these is a COMBO of innate and learnt navigation techniques?

• Using landmarks

• Using familiar smells

• Using magnetoreception to recognise local magnetic field maps

• Using magnetoreception to move North or South

What makes a behaviour/response innate?

• An organism is born with it

• It improves over time

• It requires parents/community to teach it

• It is not controlled by genes

What navigation techniques could a bee use on a cloudy day?

• Navigation by stars

• Sun compass

• Local landmarks or smells

Which of these describes homing?

• Animal movement over long distances to better resources.

• Staying at a home base with lots of recources such as food and mates, forever.

• Returning home after travelling away from it to get resources not available at home.

Name the orientation response: a bird smells a familiar scent of home and moves towards it.

• Chemokinesis

• Positive chemotaxis

• Negative chemotaxis

• Positive chemokinesis

Name the orientation response: A worm feels too hot so it starts turning more often.

• Positive thermotaxis

• Negative thermotaxis

• Thermokinesis AND Klinokinesis

• Thermokinesis AND Orthokinesis

What makes a response/behaviour learnt?

• It is controlled by genes

• An organism knows how to do it from birth

• An organism has to pick it up from its parents/community

• It doesn't improve over time

To be successful and pass on its genes an organism must:

• Survive

• Find a mate

• Survive AND find a mate
