The terms commensalism and mutualism have the same meaning and are interchangeable.  select the best answer from the choices providedtf

The correct choice is F which means the given statement is false.

Commensalism and mutualism both are symbiotic relationships but can not be used interchangeably.

Commensalism: It is the relationship between two species in which one get benefited from other specie but the second specie neither gets benefit nor gets harm. For example remora fish use shark for the transportation while shark do not any benefit from this transport nor get any harm from the remora.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
