If an ant walks across chemical, what type of poisoning is likely to occur?

When an ant walks across a chemical, the likelihood of poisoning that occurs is primarily due to contact with the chemical on its body, which aligns with the concept of contact poisoning. Insects, including ants, can absorb toxic substances through their exoskeletons, leading to direct effects from the chemical.

Contact poisoning happens when a toxic substance comes into direct contact with the skin or exoskeleton of an organism. In the case of ants, their bodies are often exposed to chemicals on surfaces they traverse, resulting in the absorption of harmful agents that can lead to their demise without any ingestion necessary.

Stomach poisoning refers to the ingestion of toxic materials, which is not applicable in this scenario since the ant is merely walking over the chemical rather than consuming it. Similarly, systemic poisoning involves toxins that spread throughout the body after being ingested or absorbed, which again does not fit the context of just walking over a chemical. Neurological poisoning typically affects the nervous system and usually results from ingestion or specific types of chemicals that target the nervous system, but this is not the primary concern when considering contact with a chemical substance in the environment.
