While there were many species of mites, springtails, and other tiny bugs in our bin, we were missing predators. I ordered a few million nematodes (a kind of tiny roundworm) by mail. Within a few weeks (long enough for the adult flies to die off and their larva to have been eaten) we had a fly-free bin.
All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Single-celled organisms use cell division as their method of reproduction. Somatic cells divide regularly; all human cells (except for the cells that produce eggs and sperm) are somatic cells.
Single celled organisms increase their numbers by dividing and making more cells like themselves. Cell Division . When cells are dividing, they grow in size for a bit and then split in two. The cells must make copies of their chromosomes (the information storing part of the cell) before they split. Bacteria only have one chromosome.
