Explanation:

Insects are a diverse group of animals that make up a significant portion of the animal kingdom. They are recognised as concrete objects which means they are tangible and can be seen, touched, and observed. Insect classification is an important aspect of entomology, the study of insects.

Classification of insects:

Insect classification involves identifying, describing and categorising insects based on their physical characteristics such as body structure, wings, legs, antennae, and mouthparts. Insects can be classified into different categories based on their characteristics. The most commonly used classification system for insects is the Linnaean classification system, which ranks organisms based on their biological characteristics.

Rank or category:

Insects are given a rank or category based on their characteristics. The categories range from species, genus, family, order, class, phylum to kingdom. The rank of an insect is determined by its physical characteristics, such as the number of legs, wings, and antennae. For example, the order Hymenoptera includes insects with two pairs of wings and well-developed mouthparts for biting and chewing. This order includes ants, bees, and wasps.

Importance of classification:

The classification of insects is important as it helps scientists to study and understand the diversity of insects. It also helps in identifying new species and understanding their biological characteristics. Classification also aids in pest control, as it helps to identify the insects that cause harm to crops and other plants.

Conclusion:

In summary, insects are recognisable concrete objects that can be classified based on their physical characteristics. The classification of insects helps scientists to understand their diversity and biological characteristics, aids in identifying new species, and assists in pest control.

Taxonomic categories  and hierarchy can be illustrated by an example. Insects  represent a group of organisms sharing common features like three pairs of jointed legs. It means insects are recognisable concrete objects which can be classified and thus are given in a rank or category.
