Assigning a '+' sign for beneficial interaction, '-' sign for detrimental and '0' for neutral interaction, outcomes of competition can be represented as:

Options

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

Answer

To solve the question regarding the representation of outcomes of competition using '+' for beneficial interactions, '-' for detrimental interactions, and '0' for neutral interactions, we can analyze different types of ecological interactions. Here’s a step-by-step breakdown:

### Step 1: Understand the Types of Interactions
- **Commensalism**: One organism benefits while the other is unaffected.
- **Parasitism**: One organism benefits at the expense of another, causing harm.
- **Mutualism**: Both organisms benefit from the interaction.
- **Amensalism**: One organism is inhibited or harmed while the other is unaffected.

### Step 2: Assign Signs to Each Interaction
- **Commensalism**:
- Beneficial for one organism: **+**
- Unaffected for the other organism: **0**
- Representation: **+ and 0**

- **Parasitism**:
- Beneficial for the parasite: **+**
- Detrimental for the host: **-**
- Representation: **+ and -**

- **Mutualism**:
- Beneficial for both organisms: **+**
- Representation: **+ and +**

- **Amensalism**:
- Detrimental for one organism: **-**
- Unaffected for the other organism: **0**
- Representation: **- and 0**

### Step 3: Identify the Outcome of Competition
In the context of competition:
- When two species compete, one may be inhibited or removed from the population while the other survives.
- This interaction can be represented as:
- Detrimental for the inhibited species: **-**
- Unaffected for the surviving species: **0**
- Therefore, the representation for competition is **- and 0**.

### Conclusion
The outcome of competition can be represented as **- and 0**, indicating that one species is harmed while the other is unaffected.
