The sign + is used to indicate an association where an organism gains, while 0 is used where an organism is unaffected. An association indicated as +0 is known as _______
- A) predation
- B) commensalism
- C) parasitism
- D) competition
Correct Answer: B) commensalism
Explanation
The question is asking about the meaning of an association indicated by the sign +0. The + sign is used to indicate a relationship where an organism gains, while 0 is used when an organism is unaffected. So, the combination of + and 0 indicates an association where one organism benefits while the other is not affected. This type of association is known as commensalism, which is a type of symbiotic relationship between two organisms in which one organism benefits, while the other organism is neither helped nor harmed. In this relationship, the organism that benefits is called the commensal, while the other organism is called the host. For example, a bird building its nest in a tree is an example of commensalism. The bird benefits by having a safe place to lay eggs and raise its young, while the tree is not affected by the bird's presence. In summary, an association indicated as +0 is known as commensalism, which is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed.
