Classification involves hierarchy of steps in which each step represents taxonomic category. Each taxonomic category is referred to as a unit of classification and is commonly termed as taxon. Taxonomic hierarchy is a system of arranging all taxonomic categories in descending order with kingdom at the top and species at the base.

As we go up the taxonomical hierarchy, the number of individuals.' increases but the number of common characteristics goes on decreasing.

Q. If two organisms are in the same phylum, then the two organisms belong to the same

Reason : Taxonomic hierarchy is arrangement of all taxonomic categories in descending order from kingdom to species.

There are millions of living organisms on earth. All these living organisms differ in shape, size, colour, habitat and many other characteristics. To understand their origin, diversity, distribution and inter relationship, the scientists have devised mechanisms to classify all of them. Classification of living organisms help in revealing the relationship between various organisms. It also helps in making study of organisms easy and organized.

Direction : In the following questions the Assertions (A) and Reasons (R) have been put forward. Read both the statements and choose the correct option from the following:

Assertion : The term systematics refers to the diversity of different kinds of organisms and their relationship.

Reason : Systematics deals with the identification, naming and classification of the organisms into groups.

Systematics is a branch of science in which different features of species, diversities, and relationships with other species are studied. It also deals with identification, nomenclature, classification and evolutionary relationships between species.

Q. The biochemical reactions which are concerned with breakdown of complex organic substances into simpler substances are collectively called

All living organisms are made of chemicals. These chemicals are constantly being made and changed into some other biomolecules. These conversions of chemicals into biomolecules are called chemical reactions or metabolic reactions. There are thousands of metabolic reactions occurring simultaneously inside all living organisms, be they unicellular or multicellular. All plants, animals, fungi and microbes exhibit metabolism.

Q. An example of anabolic reaction is
