Final answer:
The merits of Whittaker's classification include accuracy and comprehensive understanding of biodiversity, while the demerits involve difficulties in classification and changing scientific knowledge
Step-by-step explanation:
Whittaker's classification is a system that categorizes living organisms into five kingdoms based on their characteristics. The merits of this classification include providing a more accurate and comprehensive classification system, facilitating the study of biodiversity, and helping scientists understand the evolution of different species. However, there are also some demerits to Whittaker's classification, such as the difficulty in classifying organisms with overlapping characteristics and the ever-evolving nature of scientific knowledge.
