The correct Answer is:

To solve the question, we need to identify the incorrect statement among the provided options regarding living and non-living things. Here’s a step-by-step breakdown of the solution: ### Step 1: Understand the Concept of Growth - **Statement 1:** Non-living things can grow extrinsically. - **Explanation:** Extrinsic growth refers to the increase in mass from external sources. Non-living things can indeed exhibit this type of growth, such as crystals growing larger by accumulating more material from their environment. This statement is correct. ### Step 2: Analyze Reproduction in Living Organisms - **Statement 2:** Reproduction is not the defining feature of living organisms. - **Explanation:** While reproduction is a characteristic of living organisms, it is not the sole defining feature. For example, certain unicellular organisms can increase in number without traditional reproduction. Thus, this statement is also correct. ### Step 3: Evaluate Metabolic Reactions - **Statement 3:** An isolated metabolic reaction outside the body of an organism is non-living. - **Explanation:** Metabolism is a defining feature of living organisms. If a metabolic reaction occurs in a test tube (isolated from an organism), it is still a metabolic reaction and can be considered a living process. Therefore, this statement is incorrect. ### Step 4: Consider Self-Consistency in Organisms - **Statement 4:** Humans are the only organisms that have self-consistency. - **Explanation:** All living organisms have the ability to sense their environment and respond to stimuli. While humans may have advanced cognitive abilities, this statement is misleading as it implies exclusivity. However, it is generally accepted that humans have a unique level of self-awareness and consistency. This statement is somewhat correct but can be debated. ### Conclusion After analyzing all the statements, the incorrect statement is **Statement 3**: "An isolated metabolic reaction outside the body of an organism is non-living." ### Final Answer The incorrect statement is **Option 3**. ---
