LIFE DEPENDS ON ADAPTATIONS 



compete and they grow very quickly. They usually 



have deep, tough roots which help them to crowd out 



other plants by steal- 

 ing their water sup- 

 ply. Choose some 

 weed and note all the 

 adaptations you can 

 find. You will soon 

 see why it is so suc- 

 cessful in life. 



We can also show 

 that animal success is 

 due to adaptations. 

 Take any animal you 

 know and name over 

 the ways it is fitted 

 for the life it leads. 

 Hoofs, claws, furry or 

 hairy coats, feathers or 

 shells, wings, fins, flip- 

 pers or legs, different 



types of teeth, all these and many more you might name 



as adaptive structures.
