mud in Saltmarsh
Saltmarshes have lots of mud, called pluff mud. When plants
and animals die in the saltmarsh they fall to the mud and
are eaten by scavengers and decomposed by bacteria.
Decomposition makes the soil rich in nutrients and a good
place for plants to grow. Decomposition also produces as a
byproduct sulfur gas, and it is this gas that makes saltmarshes smell like rotten eggs. Decomposition may
produce strange smells, but it is important to sustaining
life in the saltmarsh and all other habitats.
