How do decomposers recycle nutrients within ecosystems?

 

The complex organic molecules are broken down by them to get energy. 

The individual components of these compex molecules are SET FREE in the environment ( air, soil , water ). 

Thus these are now FREE for recycling . 
example - A protein molecule is a very compex and big one with C,H,O, AND N in addition it may contain other atoms such a Fe , S as well ! It has some energy stored in it . 

When it is decomposed , all the individual elements mentioned above in capital letters are released for recycling . 

This is equally true for a dead tree .

Ifound this on google “according to the findings, a foramen magnum positioned toward the base of the skull is found not only in humans, but in other habitually bipedal mammals as well.” i hope this you for what your looking for
