Question

1. what is commensalism?

a symbiotic relationship in which one member benefits, and one member is harmed
a symbiotic relationship in which neither member benefits
a symbiotic relationship in which one member benefits
a symbiotic relationship in which both members benefits

Explanation:

Commensalism is a type of symbiotic interaction where one organism gains a benefit, while the other organism is neither helped nor harmed. Let's analyze each option:

• The first option describes parasitism (one harmed, one benefits).
• The second option does not match any standard symbiotic relationship.
• The third option correctly identifies that one member benefits (the other is unaffected, which is implied in the definition of commensalism as a symbiotic relationship).
• The fourth option describes mutualism (both members benefit).

Answer:

a symbiotic relationship in which one member benefits
