Question

Choose a correct option that shows an interaction in which one species benefits while the other is neither harmed nor benefitted.

• A. Mycorrhizal associations between fungi and roots of higher plants
• B. Sea anemone and clownfish
• C. Abingdon tortoises and goats in the Galapagos Island
• D. Cuscuta on hedge plants

Hint:

Commensalism is a type of symbiotic relationship where one species benefits while the other is unaffected.

Answer 1

The Correct Option is A

Step 1: Understanding the interaction types.
The question asks for an interaction in which one species benefits and the other is neutral. This type of relationship is called "commensalism."
Step 2: Analysis of the options.

• (A) Mycorrhizal associations between fungi and roots of higher plants: Correct. The fungi benefit from the plant roots by receiving nutrients, while the plants are not harmed and can often benefit from enhanced nutrient uptake.
• (B) Sea anemone and clownfish: Incorrect. This is a mutualistic relationship where both species benefit.
• (C) Abingdon tortoises and goats in the Galapagos Island: Incorrect. This is a case of competition where both species compete for resources.
• (D) Cuscuta on hedge plants: Incorrect. Cuscuta is parasitic and harms the plants by drawing nutrients.

Step 3: Conclusion.
The correct answer is (A) Mycorrhizal associations between fungi and roots of higher plants, as it is a commensalistic relationship.
Final Answer: (A) Mycorrhizal associations between fungi and roots of higher plants.
