Explaination-
Mutualism- Both species + (when two organisms of different species “work together,” each benefiting from the relationship)
Commensalism- one species +, other is O. An association between two organisms in which one benefits and the other derives neither benefit nor harm.
Amensalism- one species -, other is O. One is destroyed or inhibited, and the other remains unaffected
Parasitism- One +, other -, a relationship between the two living species in which one organism is benefitted at the expense of the other
