- A
+,+ -,- +,o Parasitism Competition Mutualism - B
+,+ -,- +,o Predation Competition Commensalism - C
+,+ -,- +,o Mutualism Competition Commensalism - D
+,+ -,- +,o Mutualism Parasitism Amensalism
Answer & Solution
Correct Answer
(C) +,+ -,- +,o Mutualism Competition Commensalism
Step-by-step Solution
Detailed explanation
(C)
,
Both the species benefits in case of mutualism. Only one of the interacting species benefits in case of predation and parasitism and the interaction is detrimental to the other species and in case of competition, the interaction is detrimental to the other species and in case of competition, the interaction is detrimental to both the species. In commensalism, one of the interacting species is benefited while other is neither benefited nor harmed.
