What ecological term describes a symbiotic relationship where one species benefits while the other species is neither helped nor harmed?
Answer and explanation
Correct answer: C. Commensalism
- Step 1: Commensalism is a (+/0) relationship where one partner benefits and the host is unaffected (e.g. epiphytic orchids on tree branches). Step 2. Mutualism is (+/+), parasitism is (+/-), and amensalism is (-/0). Answer: Commensalism. Why not the others: Commensalism specifically denotes benefit to one without impact on the other.
