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.
Cellular division, or mitosis, produces two daughter cells that are identical to the parent cell. As explained by Clinton Community College, mitosis allows multicellular organisms to grow and repair damaged tissue. Daughter cells are also produced during meiosis, which is a special type of cell division that enables organisms to sexually reproduce. Daughter cells produced in meiosis have one half the number of chromosomes as the parent cell.
