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.
In order to make new cells, all cells must undergo cell division, or cell reproduction. In prokaryotes, single-celled organisms without a nucleus, cell division occurs by binary fission. This process is very simple and includes the duplication of chromosomal DNA (DNA replication) followed by cytokinesis or the splitting of the cell into two new cells. Binary fission results in two identical daughter cells.
