There are 36 biodiversity hotspots on our planet, and these areas are dazzling, unique, and full of life. Plants, animals, and other living organisms that populate these places are rare and many of them are only found in these specific geographic areas.
How many biodiversity zones are there?
Many of these are heavily threatened by habitat loss and other human activities. These areas are the biodiversity hotspots, 36 regions where success in conserving species can have an enormous impact in securing our global biodiversity.
How many biodiversity centers are there in the world?
Map showing the 17 megadiverse countries of the world. Understanding megadiversity starts with understanding biodiversity. Biodiversity includes all of the plant and animal species on the planet, their genetic differences, and the ecosystems where they form interconnected communities.
How many hotspots are there in the world?
There are currently 36 recognized biodiversity hotspots. These are Earth’s most biologically rich—yet threatened—terrestrial regions. To qualify as a biodiversity hotspot, an area must meet two strict criteria: Contain at least 1,500 species of vascular plants found nowhere else on Earth (known as “endemic” species).
What is ecological diversity and its types?
Ecosystem diversity deals with the study of different ecosystems in a certain location and their overall effects on humans and the environment as a whole. It is one of the types of biodiversity along with species diversity, genetic diversity, and functional diversity.
How many eco zones are there in India?
India has a variety of landscapes and climate conditions and this is reflected in the development of different soils and types of vegetation. Based on 50 years of climate data and an up-to-date soil database, the country has been divided into 20 agro-ecological zones (AEZs).
How many biodiversity are there in India?
Which is the biodiversity hotspot in India? India hosts 4 biodiversity hotspots: the Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland (Includes Nicobar group of Islands). These hotspots have numerous endemic species.
Which of the given country has maximum ecological diversity?
Brazil is the only country with highest biodiversity. Biodiversity accounts one-tenth of the world’s overall species.
What percentage of the total 5% biodiversity of the earth is found in India?
India is one of 17 mega-biodiverse countries in the world. With only 2.4 percent of the earth’s land area, it accounts for 7-8 percent of the world’s recorded species.
Where is the world’s largest biological diversity found?
Brazil is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savanna-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.
How many biological hotspots are there in India?
India has four biodiversity hotspots, i.e., Eastern Himalayas, Western Himalayas, Western Ghats and Andaman and Nicobar Islands.
How many biodiversity hotspots are there in Pakistan?
As a consequence of these geographical and climatic factors, Pakistan has been divided into 10 major ecological or vegetative zones.
Why India is known as Mega Diversity nation?
India is known for its rich heritage of biological diversity, having already documented more than 91,000 species of animals and 45,500 species of plants in its 10 biogeographical regions. Almost 6,500 native plants are still widely used in indigenous health care systems.
What is ecosystem diversity class 12?
Answer: Ecosystem diversity deals with the variations in ecosystems within a geographical location and their overall impact on human existence and the environment. It is a type of biodiversity which refers to variation in species rather than ecosystems.
What are the three different types of ecological diversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.
How many living things have been discovered on Earth?
Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects.
