Question

How does mutualism compare with commensalism?

Answer 1

Answer:

Choice C: In mutualism, both organisms benefit, whereas commensalism benefits one organism without benefiting or harming the other

Explanation:

Symbiotic relationships describe the various ways organisms interact with each other. There are 5 common ones:

• Mutualism
• Commensalism
• Parasitism
• Predation
• Competition

We are asked to compare mutualism and commensalism, so we can focus on just these relationships.

In mutualism, both organisms benefit. An example is bees and flowers. Bees search for nectar in flowers and pollen from the flower attaches to the bee. As the bees fly,  they spread the pollen and pollinate other flowers.  The bees use the nectar to make honey and the flowers can reproduce.

In commensalism, one organism benefits while the other organism is not harmed or benefitted. An example is barnacles and whales. Barnacles attach to whales and they can move around and find food. The barnacle receives transportation and food. The whale remains unharmed but does not benefit.

The correct answer is Choice C: In mutualism, both organisms benefit, whereas commensalism benefits one organism without benefiting or harming the other.
