~ DECOMPOSER & DECOMPOSITION ~
ANIMALS ARE NOT DECOMPOSERS
BREAK DOWN INTO SMALLER PIECES
SPEEDS UP DECOMPOSITION
FUNGI BACTERIA
CARBON DIOXIDE NUTRIENTS WATER & MINERAL SALTS
OBTAIN ENERGY & ABSORB NUTRIENTS FROM
THE DEAD AND WASTE MATTER WHICH THEY BREAK DOWN
NOT PILE UP ON EARTH
....MINERAL SALTS WHICH CAN BE USED BY PLANTS
