Question

Identify the biological interaction among two species in which one of the species is gaining benefits while the other species is neither benefited nor harmful.

• A. Commensalism
• B. Mutualism
• C. Parasitism
• D. Amensalism

Hint:

Map out the interactions with symbols for quick reference:
- Commensalism: \((+, 0)\)
- Amensalism: \((-, 0)\)
- Mutualism: \((+, +)\)
- Parasitism: \((+, -)\)

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Interspecific interactions describe the biological relationships between different species living together in an ecosystem. These interactions can be positive, negative, or neutral.

Step 2: Detailed Explanation:
- Commensalism is a \((+, 0)\) interaction where one species benefits from the relationship while the other species is unaffected (neither helped nor harmed). An example is epiphytes growing on forest tree trunks.
- Mutualism is a \((+, +)\) interaction where both species benefit.
- Parasitism is a \((+, -)\) interaction where one benefits at the expense of the host.
- Amensalism is a \((-, 0)\) interaction where one species is inhibited or destroyed while the other remains unaffected.

Step 3: Final Answer:
The interaction described is commensalism.
