If a superior competitor is removed from the area , there is always an increased population of the otherwise exploited species ". Above given phenomenon is according to –

Options

A. Principal of competitive exclusion.
B. Principal of resource partioning.
C. Principal of competitive release.
D. More than one option is correct .

Answer

To solve the question, "If a superior competitor is removed from the area, there is always an increased population of the otherwise exploited species," we need to identify the phenomenon that describes this situation. Let's go through the options step by step:

### Step 1: Understand the Question
The question states that when a superior competitor is removed, the population of the otherwise exploited species increases. This indicates a relationship between competition and population dynamics.

**Hint:** Focus on how the removal of a competitor affects the populations of other species.

### Step 2: Analyze Option 1 - Principle of Competitive Exclusion
The principle of competitive exclusion states that two species competing for the same resources cannot coexist at constant population values. One will outcompete the other.

**Conclusion:** This option does not explain the increase in the population of the exploited species after the removal of a superior competitor.

**Hint:** Consider whether this principle allows for coexistence or population increase.

### Step 3: Analyze Option 2 - Principle of Resource Partitioning
The principle of resource partitioning suggests that species can coexist by dividing resources or niches to minimize competition.

**Conclusion:** This option does not directly relate to the increase in population after a competitor is removed, as it focuses on coexistence rather than population increase.

**Hint:** Think about whether this principle addresses the removal of competitors.

### Step 4: Analyze Option 3 - Principle of Competitive Release
The principle of competitive release occurs when a superior competitor is removed from an environment, allowing other species that were previously suppressed by competition to thrive and increase in population.

**Conclusion:** This option directly explains the phenomenon described in the question, as it indicates that the removal of a superior competitor leads to an increase in the population of otherwise exploited species.

**Hint:** Look for a principle that explains the effects of removing a competitor on population dynamics.

### Step 5: Analyze Option 4 - More than One Option is Correct
This option suggests that multiple principles could explain the phenomenon. However, since we have identified that only one principle (competitive release) accurately describes the situation, this option is incorrect.

**Conclusion:** This option does not apply as we have determined that only one principle fits the scenario.

### Final Answer
The correct answer is **Option 3: Principle of Competitive Release**. This principle explains that the removal of a superior competitor allows other species to increase in population.
