Question

Which of the following would be considered. symbiotic interactions?

O A tapeworm embedded in the intestine of a human
O A clown fish that lives in the tentacles of an anemone
O A barnacle and the mussel species that outcompetes it for space and food
O A legume, and the Rhizobium bacterial nodules in its roots

Answer 1

Out of the options provided, symbiotic interactions include the clownfish living in the tentacles of an anemone and the mutualistic relationship between a legume and Rhizobium bacteria forming nodules on its roots. Both represent symbiotic mutualism where the species involved mutually benefit from the interaction.

Step-by-step explanation:

Which of the following would be considered symbiotic interactions? A symbiotic relationship is one in which organisms from two separate species depend on each other for their survival. Out of the options provided, interactions that are symbiotic include:

• A clownfish that lives in the tentacles of an anemone
• A legume and the Rhizobium bacterial nodules in its roots

The clownfish and the sea anemone engage in a mutualistic relationship because both species benefit. The clownfish receive protection from predators thanks to the anemone's stinging tentacles, while the anemone is defended against polyp-eating fish by the clownfish. Similarly, the legume plant forms mutualistic nodules with Rhizobium bacteria, which fix atmospheric nitrogen, supplying the plant with usable nitrogen and in return obtaining carbohydrates and a protected environment from the plant.
