Answer 1

Answer:

D) Family

The Kingdom is the largest and most inclusive of the taxonomic categories. Species is the smallest and least inclusive of the taxonomic categories.

Answer 2

The taxonomic level that is most inclusive of organisms is CLASS. (OPTION C)

TAXONOMIC LEVEL - CLASS

• The organisms are divided into different taxonomic categories as domain, kingdom, phylum, class, order, family, genus, species.
• The classification is hierarchical with the increase in specificity among the organisms.
• Each category classification, the similarity between the organisms increases.
• The Domain is the most inclusive level with organisms sharing basic similarities whereas species is the most exclusive and smallest level of classification.
• The inclusive nature of the classification decreases from kingdom to species as - Kingdom > Phylum > Class > Order > Family > Genus >  Species.
• Therefore, Order is more inclusive with organisms sharing less common similarities than lower hierarchical levels.
