MCQs on Diversity in the Living World

Importance of Diversity in the Living World for NEETs

NEET is a prestigious entrance exam for medical which enables students to apply for medical colleges in the country. The pattern of the exam is objective questions based on chapters from the syllabus. NEET exam is carried out in four sections- Physics, Chemistry, Botany, and Zoology. The total number of questions in the paper is 180 with a total scorable of 720. Half of the total weightage is given to the subject biology that makes 50% of the questions from the subject biology. Moreover, diversity in the living world is the first unit in the biology syllabus. This chapter has good marks weightage in the biology paper and with effective preparation and practice, students can score higher marks in the NEET exam.


Diversity in the Living World for NEET

Our planet is dominated and co inhabited by millions of organisms. Some warmer regions show an exceptionally high diversity of organisms, while some colder regions are a host to only fewer species. The warmer regions with exceptionally high biodiversity are referred to as regions of mega biodiversity. Trillions of years ago, when life just started on Earth, it has only a few forms of life. But, after so many years, organisms have evolved into higher and higher species to survive and continue their existence. Some species have been left behind and have gone extinct but those who have survived are continuously evolving with the changing environments.


Therefore, it is important to group organisms on the basis of their similarities and dissimilarities. The system of classifying living organisms into groups is known as classification. Classification in the living world is done on various parameters. The widely accepted classification system across the world is a five-kingdom classification. The Hierarchy of classification in the five-kingdom system is-

  • Kingdom

  • Phylum

  • Class

  • Order

  • Family

  • Genus

  • Species


Now we will take a look at some solved MCQs based on the chapter Diversity in the Living World

Necessity of Studying Diversity in the Living World

This contains descriptions of the classification, attributes, properties, and exceptional features of living organisms. In addition to learning about biological structures, students will gain knowledge about the reproduction and structural organization of animals and plants. Therefore, it is important that students have a solid understanding of the chapters of the unit Diversity In The Living World. Preparation is imperative for this topic because all examples, features, and important points need to be well known. NEET questions in today's world will be diverse, but if one knows all these, they will be easy to deal with.

FAQs (Frequently Asked Questions)

1. What is the Number of Questions that Come from Diversity in the Living World?

The exam paper includes 180 questions, scoring 720 points total. In the subject biology, 50% of the questions are related to the subject biology, which makes up half of the total weightage.

2. Which Person gave the Classification of Five Kingdoms?

Whittaker proposed a five-kingdom system: Monera, Protista, Fungi, Plantae, Animalia.

3. What does Living World Diversity mean?

A variety of living organisms make up the living world. There is a direct connection between all living organisms on the planet today and all organisms that have ever existed. This information humbled mankind and launched cultural movements for biodiversity conservation.

 4. What is the Importance of Diversity to All Living Things?

Every species in an ecosystem, regardless of its size, plays an important role in boosting ecosystem productivity. A greater variety of crops can be obtained through a larger number of plant species. This ensures a more sustainable environment for all types of animals.

5. How Diverse is the Living World?

The number of species on earth is estimated to exceed 5 million. Out of these, about 1.7 million species have been described and are known. It is estimated that there are new species described every year. Since it is nearly impossible to study all organisms, they are classified into groups for convenience.

6. What do You mean by the Living World?

Our living world is characterized by all that we see and experience around us. Life consists of all organisms which cannot be seen, including animals, plants, and microorganisms. While the general composition has changed over billions of years, the fundamental structure has not changed. Basically, organic matter and inorganic matter remain the main components of the earth.
