Organisms such as mold or bacteria growing in it.

If conditions permit or cross contamination occurs food may be fertile ground for the growth of:
Bacteria Like: Salmonella spp., Enterohaemorrhagic Escherichia coli, Campylobacter jejuni, Yersinia enterocolitica, Listeria monocytogenes, Bacillus anthracis, Bacillus cereus, Staphlococcus aureus, Clostridium botulinum, Clostridium perfringens, Vibrio vulnificus, Vibrio parahaemolyticus
Viruses like hepatitis A virus, Norwalk viruses, Rotavirus
Parasites like Toxoplasma gondii, Cryptosporidia, Giardia spp., Trichinella spiralis, Taenia solium, Anisakis spp.

No, bones from a chicken in a chicken filet would not be a biological contaminant. Human blood, human spit, human nasal secretions, or other bio material in your chicken filet would be a biological contaminant.

A similar term is "contaminant transport". It means the path that a contaminant moves from its beginning to its final resting place, and all the physical, chemical and biological processes that might change it on its journey.
A biological contaminant that is one of the biggest sources of air pollutionis mold. Molds can be found everywhere and mold spores are common components in household and workplace dust.

The biological and physical chemical application of oxidation and reduction include contaminant reduction and mineralization of organic matter.
This depends on the food - breads, beers and any fermented food must have yeast in it as the yeast is what does the fermenting. However, in a non-fermented food, a yeast could be a biological contaminant.
bacteria or other rotten food
If you have an example of a common biological apparatus you are probably holding a beaker. The beaker is the most common and well recognized biological apparatus.
what is the purpose, strenghts, weaknesses and provide an example for biological?
A contaminant reduces the melting point of a solid.
