The kingdom Monera comprises of both autotrophic and heterotrophic organisms ,but I don't get the logic behind why the seperation of heterotrophic and autotrophic organisms is considered as the merit of 5kingdom classification
Answers
Answer:
Scientists have been trying to classify living organisms in various ways for centuries. In fact, even Aristotle classified living organisms on the basis whether they lived on land, water or air. But biologists wanted a broader system of classifying living organisms. Hence came the five kingdom classification. Let us look at it in detail.Very early on, scientists began grouping the living organisms under different categories. Some biologists classified organisms into plants and animals. Ernst Haeckel, Robert Whittaker, and Carl Woese are some biologists who attempted a broader system of classification. Amongst these, the Five Kingdom Classification proposed by Robert Whittaker stood out and is widely used.
Whitaker proposed that organisms should be broadly divided into kingdoms, based on certain characters like the structure of the cell, mode of nutrition, the source of nutrition, interrelationship, body organization, and reproduction. According to this system, there are five main kingdoms. They are:
- Kingdom Monera
- Kingdom Protista
- Kingdom Fungi
- Kingdom Animalia
- Kingdom Plantae
Explanation:
Kingdoms are divided into subgroups at various levels. The following flowchart shows the hierarchy of classification.
Kingdom → Phylum → Class → Order → Family → Genus → Species
