Final answer:
Having commensal arthropods means there are beneficial arthropods that interact with your environment or your body without causing you any harm, helping maintain ecological balance and contributing to pest control.
Step-by-step explanation:
If you have commensal arthropods, it means you have arthropod species living in or on your environment or body in a way that is beneficial to them, but does not harm or affect you. This type of relationship is known as commensalism.
Arthropods, creatures with jointed legs and a chitinous exoskeleton, include insects, arachnids, and crustaceans. Examples of such relationships are mites that travel on larger insects without causing them any harm, or birds like the cattle egret that eat pests stirred up by livestock without affecting the livestock themselves.
Studies have shown that commensal bacteria on our bodies play a significant role in protecting us from pathogens, aiding digestion, and even affecting our moods and weight. Likewise, commensal arthropods can be beneficial for pest control, often preying on or outcompeting harmful species naturally. Phylum Arthropoda, known for its diversity and abundance, plays various roles in ecosystems, including ecological balance and pest control.
