select the incorrect option.

Options

A. each taxonomic category is referred as unit of classification
B. the characteristic goes on decreasing from species to Kingdom
C. specificity increase from species to Kingdom
D. species such as a basic and lowest

Answer

To solve the question of selecting the incorrect option regarding taxonomical classification, we can break down the statements one by one:

1. **Statement Analysis**:
- **Statement 1**: "Each taxonomic category is referred to as a unit of classification."
- This statement is true. Taxonomic categories such as kingdom, phylum, class, order, family, genus, and species are indeed units of classification.

- **Statement 2**: "The characteristics go on decreasing from species to kingdom."
- This statement is also true. As we move from species (which has the most specific characteristics) to kingdom (which is more general), the number of shared characteristics decreases.

- **Statement 3**: "Specificity increases from species to kingdom."
- This statement is incorrect. As we move from species to kingdom, specificity actually decreases. Species are more specific than kingdoms, so this statement is reversed.

- **Statement 4**: "Species is the basic and lowest category."
- This statement is true. In taxonomical classification, species is indeed considered the most basic and lowest category.

2. **Conclusion**:
- The incorrect option is **Statement 3**, which states that specificity increases from species to kingdom. This is the opposite of what is true.

**Final Answer**: The incorrect option is **Statement 3**.
