Birds have different beak shapes & legs according to the food they eat & the environment they live in:
Organism |
Adaptation of the mouth |
Reason |
|
-Sharp & crooked (curved) beaks. -Their fingers end with sharp claws. |
To tear the prey. To catch the prey. |
|
-Long thin beaks -Long thin legs & fingers. |
To pick worms from shallow water To walk in shallow water ponds (their environment). |
|
-Wide indented beaks . -Webbed feet (called palm) |
To filter mosses from water. For swimming |
3. Adaptation of insectivorous plants.(insects eating plants).
Drosera , dieonea & halphila are predating plants.
They perform photosynthesis & make carbohydrates (their food) like all green plants.
They also catch insects & digest them. the digested insects are the source of nitrogenous material (made from nitrogen). The insectivorous plants use nitrogenous material to build their bodies.
Give an example (the name of an organism) to explain:
How an animal adapts to live in the desert.
