Chapter 7 – Diversity in Living Organisms

The following Topics and Sub-Topics are covered in this chapter and are available on MSVgo:

Introduction

Our world is home to a diverse range of living species, each with its own scale, form, climate, diet, reproduction, and other characteristics. These Kingdom Animale species are divided into various orders and classes based on their physical characteristics and environment. 

Animals live in various habitats, such as oceans, soil, deserts, trees, glaciers, land, water, ice, deserts, forests, and grasslands. Cells make up a single one of these species. 

Cells are one of the most significant features of all living beings, and they are the building blocks of existence. They are biological structural units that perform various functions. A tissue is made up of a set of these cells.

The diversity of living species can be seen all around the world. The earth’s warm and humid areas are rich in biodiversity and are known as the “zone of super biodiversity.” More than half of the world’s biodiversity is concentrated in only 12 nations, and India is one of them. 

Each individual has a distinct DNA profile. Human beings vary in their appearance and the factors that influence it, such as height, complexion, etc. When we equate ourselves to a single animal, such as a horse or a shark, we can see that we are a lot different from them, yet when a horse is related to a zebra, we see only a few distinctions. 

Classification is the division of species into classes based on their similarities and variations.

We have seen variations in living organisms for millions of years. From ape-like creatures to homo sapiens, we have progressed. We search for distinctions between species to classify them and research them as a whole. To do so, we must first settle on essential traits that will serve as the basis for classification. 

Various criteria can be used to classify living organisms, including: 

  • The existence of a nucleus 
  • Single-celled or Multicellular organisms 
  • Food production 
  • The level of organization in the bodies of photosynthesizing species.

There are two kinds of classification systems: 

  1. Carolus Linnaeus suggested the two-kingdom classification scheme, which divided species into two types: plants and animals. 
  2. H.Whittaker suggested the Five-Kingdom Classification, which classified species into five main classes: 
  • Monera 
  • Protista 
  • Fungi 
  • Plantae
  • Animalia

Evolution and organism classification are inextricably linked. Evolution is the accumulation of improvements in the body shape of animals over time in order for them to survive. In his novel “The Origin Of Species,” published in 1859, Charles Darwin introduced the concept of evolution for the first time. 

When evolution is linked to grouping, the following conclusions are drawn: 

  • Organisms of an ancient body form, known as ‘lower’ or ‘primitive,’ seem to have remained unchanged over time. 
  • ‘Higher’ or advanced species are those that have just recently developed their unique body designs.

Biodiversity refers to the abundance and complexity of life on the planet. It is our planet’s most dynamic and significant function, and life does not exist without biodiversity. 

In 1985, the word biodiversity was invented. It is vital in both natural and man-made environments. It is concerned with the biosphere, which encompasses much of nature’s diversity. It relates to differences in the plant, animal, and microbial organisms. 

The number of various species and their relative frequencies in an environment is referred to as biodiversity. It also reflects how species are organized at different stages. 

Biodiversity is essential for both ecological and economic reasons. It provides us with food, shelter, wood, clothes, and a variety of other resources. As a result, having a clear understanding of biodiversity is critical for a long-term livelihood.

Carl Linnaeus developed the binomial nomenclature scheme in taxonomy. Multiple local names render identifying an individual internationally and keeping note of the number of organisms incredibly challenging. As a result, there is a great deal of ambiguity. To clear this, a basic protocol was created. It states that each entity would have a single scientific name that will be used by all to describe it. Binomial Nomenclature is the term for the method of standardizing naming. Taxonomy includes nomenclature and classification. The first stages are concerned with finding, describing and naming species of living or fossil organisms. Binomial nomenclature is therefore an integral part of taxonomy as it is the system by which species are named. Taxonomists are people concerned with classification, including its principles, procedures and rules.

In this chapter, we learned about the types of living organisms. We learned about the nomenclature and Taxonomy of different living organisms.

1. Why is diversity in living organisms important? 

It informs us about the variety of plants and animals that exist. It sheds light on the origins of organisms and their interrelationships. It allows for the analysis of a broad range of species.

2. What is evolution and diversity? 

Evolution and diversity are the products of long-term interactions between species and their ecosystems, as well as the results of such interactions. Organisms adapt to their environments over time, and the variety of ecosystems available encourages a range of organisms that have adapted to them.

3. What is diversity class 9? 

Biodiversity, also known as biological diversity, refers to the number of living species found in a given area.

4. What are the 4 types of diversity? 

Species, genetic, ecosystem, and functional diversity are the four forms of diversity.

5. What are the benefits of diversity?

It aids in the comprehension of the relationships between various classes of species. It serves as a foundation for more research in biological sciences.
