When both organisms benefit from the intercourse.
Buffer, reasons, bad news, counterproposal, and desire to continue the relationship
Parasitic, commensalistic, mutualistic, etc.
It is when 2 organisms dont help or hurt one another
Both are a relationship between two organisms, called a symbiotic relationship. A parasitic relationship is when one organism gains at the other organism's expense. An example of a parasitic relationship is a tick. A mutualistic relationship is when both organisms gain from each other. An example of this would be honeybees and flowering plants.
Mutualistic- Both benefit Parasitic - One benefits and other suffers
Humans do have a mutualistic and pathogenic relationship with the same organism. This is the planet earth. We are constantly fighting to stay on the mutualistic side of the relationship vs the pathogenic.
A symbiotic relationship is the same as a mutualistic relationship, where both organisms benefit- For example, lions hunting for food- this enables a vast group of organisms to benefit and means that resources can be shared
symbiosis in which two organisms of different species stay near each other having both advantages.
the answer is they have a mutualistic relationship
