Step-by-step explanation:
Toxins, venoms, and poisons are various poisonous substances produced by some microorganisms such as bacteria and viruses.
Toxins are poisons that are naturally produced by organisms. They can be categorized as endotoxins or exotoxins. Endotoxins are toxins that are part of the bacterial structure and are released when the bacterium dies. Exotoxins are toxins that are secreted by bacteria and can cause damage to host cells.
Venoms are toxins that are injected by a bite or sting from animals. They are exclusive to animals and are used for defense or to capture prey.
Poisons are substances that cause death, injury, or harm to organs when an organism absorbs a sufficient quantity. They can come from a variety of sources, including the environment, microorganisms in food, and even certain plants and fungi.
