From the oceans, let’s rocket to the sky to understand about the powerful eagle, king predator of the sky.
As the video does not mentioned anything much, below is a summary of the adaptations of the eagle.
Eagles and other birds are commonly tested in Primary Science Examinations, especially with regards to their body shape, feet and beaks
Primary 6 Science Application Questions: Adaptation
Two birds, Bird A and Bird B, were kept separately in two cages as shown below.
300g of seeds and 50 ml of nectar were placed in each cage at the start of the experiment. After two days, the amount of seeds and nectar were recorded in the table shown below.
|Mass of seeds at the start of the experiment (g)||Mass of seeds at the end of the experiment (g)|
|Cage with Bird A||300||300|
|Cage with Bird B||300||100|
|Volume of nectar at the start of the experiment(ml)||Volume of the nectar at the end of the experiment(ml)|
|Cage with Bird A||50||20|
|Cage with Bird B||50||50|
(a) What can you infer about the diet of Bird A?
(b) How is Bird A adapted in its natural habitat for the diet mentioned in (a)?
(c) Why was the volume of nectar in the cage with Bird B the same at the start and at the end of the experiment?
The pictures below show a duck and a hawk.
The duck lives near water and eats small organisms found in the water.
The hawk lives on land and eats animals such as mice and rabbits.
- State one way how the beak of each bird is adapted to the bird’s diet. (2m)
- State one way how the feet of each bird are adapted to the bird’s habitat. (2m)
Stay tuned for the answers.
