I've just started learning the A2 part of AQA Biology and I'm already stuck, oops..
But can someone please explain the difference between a decomposer & a detritivore?:(
Detritovore is a an organism like miilipedes, beetles etc, that break down large matter into smaller ones.
A decomposer is stuff like bacteria and fungi which break down small matter into elements.
A detritivore is a kind of decomposer. Detritivores are things like insects which eat and digest detritus using holozoic nutrition, as in it eats things and then digests it.
Another kind of decomposer are saprobionts, fungi or bacteria which release digestive eszymes them absorb the products.
there is one crutial difference between detritivores and decomposers:
Decomposers physically eat the dead organic matter and is the method used in organisms such as worms, maggots etc.
Detrivores release enzymes to break down the organism into simple molucules and they absorb the product, this is used in fungi and bacteria etc.
