The correct Answer is:
To answer the question "Hierarchy is," we need to understand what hierarchy means in the context of biological classification. Here’s a step-by-step breakdown of the solution: ### Step-by-Step Solution: 1. **Understanding Hierarchy**: - Hierarchy in biology refers to the systematic categorization of living organisms based on shared characteristics. This system allows scientists to organize and classify the vast diversity of life. 2. **Levels of Hierarchy**: - The biological hierarchy consists of several levels, which are: - **Kingdom**: The highest taxonomic rank that groups organisms based on fundamental traits. - **Phylum**: Groups organisms based on major body plans and structural features. - **Class**: A further division within a phylum that groups organisms with similar characteristics. - **Order**: A grouping of families that share certain traits. - **Family**: A group of related genera (plural of genus). - **Genus**: A group of species that are closely related. - **Species**: The most specific level, representing a group of individuals that can interbreed. 3. **Categorization**: - The process of categorizing organisms into these levels is what defines the term "hierarchy." It is an ordered arrangement that helps in understanding the relationships and differences among various organisms. 4. **Evaluating Options**: - Now, let’s evaluate the provided options: - **Option 1**: "Categorization of group of living beings." - This is correct as hierarchy involves categorizing organisms. - **Option 2**: "Series of ordered grouping within the system." - This is also correct as hierarchy represents an ordered system of classification. - **Option 3**: "Either 1 or 2." - Since both options are correct, this option is also valid. 5. **Conclusion**: - Since both options 1 and 2 accurately describe hierarchy, the best answer is **Option 3**: "Either 1 or 2." ### Final Answer: - The answer is **Option 3**.
