1. An association between two different species where the symbiont benefits and the host is harmed is known as: a. Amensalism b. Symbiosis C. Commensalism d. Pathogenic e. Parasitism​

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this
