Re: Help! Symbiotic Relationships and Decomposers

A good example of a decomposer in the desert would be a dung beetle.

Their relationship with other animals could be termed commensalism,

since animals probably aren't affected at all by what happens to 

their dung.  A mutualistic relationship in the desert is that between

the yucca moth and yucca plant: the yucca moth is the only moth that

pollinates the yucca plant, and the yucca plant is the only place a

yucca moth will lay eggs.  As for parasites, sand fleas are well-known

desert parasites on desert animals such as camels.  I hope this will

get you started!
