Hello friends, welcome to this article. If you want to know what biodiversity is, then friend, you have come to the right post. Today, we will learn about it very well.
What is Biodiversity?
How many creatures are there on this planet? All are connected. According to an estimate by scientists, about 8.7 million species are found on our earth.
According to a report, 86% of the 8.7 million species are found on land, and 91%, or 86%, of the discoveries are still in the oceans. The catalog has yet to be made, and the species have yet to be described. However, humans have been placed at the highest place in the classification.
That is, placed on top. But humans depend on plants and animals for food, and animals are used as a source of income for many.
For example, it is used for work, farming, as a pet, and for other work. It is also done for economic gain.
It is very important to understand animals and their behavior, habitat, their characteristics, and their evolutionary relationships.
Diversity of life in the world
Trees, plants, and animals are found almost everywhere, from shallow lagoons to deep oceans, polar icebergs to hot volcanic springs, tropical rain forests, and dry deserts. A variety of species have adapted to live successfully in diverse ecosystems.
A.G. According to Tansley, the ecosystem is a community of biotic factors and abiotic factors and their interrelationships.
The presence of many species in a particular ecosystem is called biodiversity. Walter Rosen first used the term biodiversity (1985), and it’s what E.D. Wilson defined.
Our earth is full of different types of creatures, living in various environments. At present, 2.5 million species of organisms have been given scientific names.
There are more than 1.5 million animal species and 7.5 lac members, only insects. There are also 3.5 million plant species, including algae, fungi, mosses, and higher plants.
Biodiversity is made up of two words.
Bio + Diversity Bio means = living things, and Diversity means = variations.
Thus, the differences between animals, plants, crops, and their environment are called biodiversity.
We have come to know what biodiversity is, and now we will learn about the types of biodiversity.
How many types of biodiversity?
There are 3 types of biodiversity.
- Genetic diversity
- Species diversity
- Ecosystem diversity
Genetic diversity
Genetic diversity is that diversity. When there are variations in the genes of the same species, it is called genetic diversity.
Species diversity
Species diversity is diversity. When two different species live within a particular area, differences are found between them. This diversity is measured by the number of different species present in that area.
Ecosystem diversity
Different types of flora and fauna are found within any one ecosystem; thus, the diversity found is called ecosystem diversity.
What is Biodiversity, and have you learned about the types of Biodiversity? Now, we will learn about Biodiversity in India.
Biodiversity in India
- India exhibits vast biodiversity.
- India is home to 7% of the world’s flora and 6.5% of the world’s animals.
- The country’s local fauna is 62%.
- Twelve countries determined that India is a major centre of biodiversity.
- In 1999, based on forest reports, satellite data, and views of each state, the total forest area in India was 6,37,293 sq. It is spread over km. This is 19.39% of the total geographical location of the country. If it is converted into hectares, it will be 64 million hectares.
- Indian flora includes 15 thousand flowering plants, of which about 1500 species are on the verge of danger.
- There are 372 species of mammals in India.
- There are 1228 species of birds in India, which is 13% of the world’s total.
- Reptilians and amphibians include 446 and 204 species, respectively.
- Because living beings are widely spread worldwide, we need to recognize useful and harmful organisms. Various classes and names have been given to living things from an ancient activity of every human culture.
What have we learned from this?
What are biodiversity, genetic diversity, and species diversity? What is the definition of ecosystem diversity, and what is India’s biodiversity?
