Importance of Diversity in the Living World for NEETs

Globally, the humid and warm regions of the earth are regarded as having a great diversity of life. Class 11 of the biology syllabus begins with a study of diversity in the living world. The chapter carries a lot of weight. The taxonomy provides you with insights into the diverse living organisms that inhabit the Earth. Living organisms will be explained in detail, along with their classification, properties, attributes, and exceptional characteristics. Each person has a different DNA sequence. The characteristics of species may vary widely. Further, the concepts covered in this chapter will help the student comprehend upcoming biology chapters. Therefore, it is imperative that students are familiar with this chapter's concepts and theories. 


National Eligibility Entrance Test(NEET)

Medical colleges in India accept NEET as an entry requirement for their applicants. The examination is divided into objective questions based on sections of the syllabus. Physics, Chemistry, Botany, and Zoology are the four sections of the NEET. The paper has a total of 180 questions and a total score of 720. A total of 50% of the questions are from the subject biology as it receives half of the weighting. The biology syllabus is also divided into first and second units that deal with diversity in the living world. With good preparation and practice, students can score high marks on the biology paper. This chapter has good marks in the biology paper.

Diversity in the Living World

A vast number of organisms share our planet with us and dominate it. The diversity of organisms in warmer regions tends to be exceptional, while in colder regions only a few species live. A region of mega biodiversity is one when it has exceptionally high levels of biodiversity despite being warm. When life began on Earth billions of years ago, there were just a few forms of life. In the long period of time since organisms have evolved into higher and higher species, they have managed to survive and continue to exist. Many species have gone extinct due to the changing environments, but those who have survived have continued to evolve.

Classification of Living Organisms

Due to the diversity, it is important to group organisms based on what these organisms have in common and what they don't have in common. This process of organizing living organisms into distinct groups is called classification. Various parameters are taken into account when classifying living organisms. Five-kingdom classifications are commonly accepted around the world. There are five levels of classification in the five-kingdom system.

  • Kingdom

  • Phylum

  • Class

  • Order

  • Family

  • Genus

  • Species

The 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. 

Look at some solved MCQs based on the chapter diversity in the living world, which are available in a PDF on the Vedantu app or Vedantu website.

FAQs on MCQs on Diversity in the Living World

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.
