Question

which of the following would be considered symbiotic interactions? select all that apply group of answer choices a clown fish that lives in the tentacles of an anemone a tapeworm embedded in the intestine of a human a barnacle and the mussel species that outcompetes it for space and food a legume, and the rhizobium bacterial nodules in its roots

Answer 1

The clownfish and the sea anemone, the tapeworm and human, and the legume and rhizobium bacterial nodules all represent symbiotic interactions, with the first and last being mutualistic relationships, while the tapeworm and human interaction is parasitic.

Therefore, the correct options are:

• A clownfish living in the tentacles of an anemone
• A tapeworm embedded in the intestine of a human
• A legume with rhizobium bacterial nodules in its roots.

Step-by-step explanation:

Symbiotic interactions are relationships where two different species interact closely and at least one benefits. Among the given options, three can be considered symbiotic:

• A clownfish living in the tentacles of an anemone (mutualism).
• A tapeworm embedded in the intestine of a human (parasitism).
• A legume with rhizobium bacterial nodules in its roots (mutualism).

The clownfish and the sea anemone engage in a mutualistic relationship where both species benefit: the anemone provides protection to the clownfish with its stinging tentacles, while the clownfish fends off predators and provides nutrients.

The tapeworm in a human is an example of parasitism, where the tapeworm benefits at the cost of the human's health.

Lastly, the mutualistic relationship between legumes and rhizobium involves the bacteria fixing nitrogen for the plant, while the plant provides carbohydrates and a niche for the bacteria.
