Binary fission is the dividing of cells into additional cell bodies. "Binary fusion," though a commonly used phrase, is not a scientific term.
Binary fission is an asexual method of reproduction commonly found in prokaryotic organisms. In the process of binary fission, the organism duplicates its DNA and splits into two parts, each part receiving one copy of the DNA. Some organisms, such as tapeworms, use fission to continuously extend their bodies to grow larger and longer. Other organisms use a type of fission called fragmentation to break off parts of their bodies so that the fragments regenerate to form entirely new beings.Learn More

The fungi are a kingdom in the eukaryote domain. Fungi are important decomposers in all ecosystems because they can break down a wide variety of organic matter. Lignin, a component of wood, would not get broken down without fungal decomposers, so the nutrients would not be recycled.Full Answer >
Flora and fauna mean plants and animals; the word "flora" is used to discuss plant life, while the word "fauna" refers to animal life. This term is often applied to a specific biome, ecosystem or place, such as "the flora and fauna of the New Mexico desert" or "common flora and fauna of the tundra." These are just two forms of life that can exist in a place and do not include other life forms such as fungi or single-celled, non-plant and non-animal organisms such as bacteria; the general term to refer to all of the different forms of life that can exist in a specific place is "biota."Full Answer >
