Which types of agents are classified as biological weapons?

Biological weapons are defined as any pathogen or biological product that can cause disease or harm to humans, animals, or crops. The correct answer encompasses various microorganisms and biological toxins that can be weaponized. Bacteria, viruses, fungi, and toxins can be used to intentionally inflict injury or death on populations, crop systems, or livestock, making them a central focus in the domain of biological warfare.

Bacteria, such as anthrax and plague, can multiply and spread, causing widespread disease. Viruses, such as those responsible for smallpox or Ebola, have the potential to cause significant mortality and disrupt societal structures. Fungi can harm crops or cause sickness in humans and animals. Additionally, toxins, which are poisonous substances produced by living organisms, can be deployed in small quantities to achieve significant lethality or incapacitation. Thus, this classification forms a crucial understanding in identifying and countering potential biological threats in emergency response protocols.
