Predation, parasitism and commensalism share a common characteristic i.e,

Options

A. Both the intercting species are benefitted
B. Interating species live closely together
C. One of the species is benefitted while other os harmed
D. Both the species belong to same taxonomic group

Answer

To answer the question about the common characteristic shared by predation, parasitism, and commensalism, we can break it down step by step:

### Step 1: Understanding the Definitions
- **Predation**: This is an interaction where one organism (the predator) hunts and consumes another organism (the prey). For example, a tiger (predator) hunting a deer (prey).
- **Parasitism**: In this relationship, one organism (the parasite) benefits at the expense of another organism (the host). For example, a malaria parasite living in a human host.
- **Commensalism**: This is an interaction where one organism benefits while the other is neither helped nor harmed. For example, barnacles attaching to a whale.

### Step 2: Analyzing the Interactions
- In **predation**, the predator benefits while the prey is harmed (it is killed).
- In **parasitism**, the parasite benefits while the host is harmed (it suffers from disease).
- In **commensalism**, the commensal benefits while the host is unaffected.

### Step 3: Identifying Common Characteristics
- All three interactions involve close living relationships between the species involved.
- In predation and parasitism, one species benefits while the other is harmed.
- In commensalism, one species benefits while the other is neither harmed nor benefited.

### Step 4: Conclusion
The common characteristic shared by predation, parasitism, and commensalism is that **the interacting species live closely together**.

### Final Answer
The common characteristic shared by predation, parasitism, and commensalism is that **the interacting species live closely together**.
