Name the law which supports this statement; Two competing species cannot live for long duration in the same niche or habitat.The superior will eventually eliminate the inferior one.

Options

A. Allen's law
B. Mendel's law
C. Gause's competitive exclusion principle
D. Weismann's theory

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement discusses the competition between two species that occupy the same niche or habitat. It suggests that one species will eventually outcompete the other.

2. **Identifying Key Concepts**: The key concepts here are "competing species," "niche," and "habitat." The idea is that when two species compete for the same resources, one will have an advantage over the other.

3. **Explaining Competition**: In an ecosystem, resources such as food, water, and shelter are limited. When two species compete for these resources, they cannot coexist indefinitely if they are vying for the same niche.

4. **Introducing the Principle**: The principle that explains this phenomenon is known as the "Competitive Exclusion Principle." This principle states that two species competing for the same resources cannot coexist indefinitely; one will eventually outcompete and eliminate the other.

5. **Defining the Competitive Exclusion Principle**: The Competitive Exclusion Principle, often attributed to G.F. Gause, indicates that if two species are competing for the same resources, the species that is more efficient in utilizing those resources will thrive, while the other will decline in numbers.

6. **Conclusion**: Therefore, the law that supports the statement is the "Competitive Exclusion Principle."

**Final Answer**: The law that supports the statement is the Competitive Exclusion Principle.
