How do mutualism and parasitism compare
A At least one organism is helped in both cases
B At least one organism is harmed in both cases
C organisms are only harmed in both cases
D organisms are only helped in one while organisms are only harmed in the other
A) would be the only correct one from my knowledge. Mutualism is when neither Organism is harmed and both live mutually together, and Parasitism is when an Organism is living on the, ex. nutrients, of the host.
