MCQs for Class 11th and NEET on The Living World

Biology is the scientific study of living organisms and processes. There is an incredible diversity of living organisms around the globe. The distinction between inanimate substances and living beings was observed by early man. Some inanimate matter (wind, sea, fire, etc.) and some animals and plants were deified by early man. The emotion of awe or dread induced by all such forms of inanimate and live beings was a common feature. Living species, including humans, were first described much later in human history. Societies that had an anthropocentric approach to biology could only make limited advances in biological understanding.
