The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question states that two organisms belonging to competing species cannot coexist for a long duration in the same niche or habitat. We need to identify the law that explains this phenomenon. 2. **Concept of Competition**: In ecology, competition occurs when two or more species compete for the same resources (like food, space, or light) in an environment. When species compete, one may be more efficient in utilizing resources, which can lead to the decline or elimination of the less efficient species. 3. **Gauss's Competitive Exclusion Principle**: This principle, proposed by the ecologist G.F. Gauss, states that two species competing for the same resources cannot coexist indefinitely. One species will outcompete the other, leading to the eventual exclusion of the inferior competitor. 4. **Resource Partitioning**: For two species to coexist, they must partition their resources. This means they must adapt in such a way that they utilize different resources or the same resources at different times or in different ways. 5. **Conclusion**: The law that describes the inability of two competing species to coexist in the same niche is known as **Gauss's Competitive Exclusion Principle**. **Final Answer**: Gauss's Competitive Exclusion Principle. ---

Study the following statements and select the incorrect ones. (i) Pyramids of energy and yearly biomass production can never be inverted, since this would violate the laws of thermodynamics. (ii) Pyramids of standing crop and numbers can be inverted, since the number of organisms at a time does not indicate the amount of energy flowing through the system. (iii) There are certain limitations of ecological pyramids such as they do not take into account the same species belonging to two or more trophic levels. (iv) Saprohytes are not given any place in ecological pyramids even though they play a vital role in the ecosystem.
