How does diversity vary in India?
Because of its vast size and location, India has a varied bio-diversity. Ranging from flora and fauna that thrive in the tropics, it has those which survive in sub-zero temperatures, in the northern regions. The Biological Diversity Act of 2002 was passed by the Indian Parliament.

What is variation in biodiversity?
Biological diversity, often shortened to biodiversity, is the variation of life at all levels of biological organization, referring not only to the sum total of life forms across an area, but also to the range of differences between those forms.
Why does biodiversity vary throughout the world?
The creatures that survive have fewer breeding partners, so genetic diversity declines. Pollution, overfishing, and overhunting have also caused a drop in biodiversity. Global climate change—the latest rise in the average temperature around the globe, linked to human activity—is also a factor.

What is the importance of biodiversity in India?
Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
What is biodiversity What is its usefulness describe biodiversity of India?
Biodiversity describes the richness and variety of life on earth. It is the most complex and important feature of our planet. Without biodiversity, life would not sustain. The term biodiversity was coined in 1985. It is important in natural as well as artificial ecosystems.
What affects variation in biodiversity?
Genetic diversity influences biodiversity, and thus NCP, in two main ways: (1) through standing genetic variation (that is, the particular combination of genes and alleles present at a given time in a given place); and (2) through contemporary evolution (that is, ongoing evolutionary changes that affect the genetic …
Why is variation important to biodiversity?
Abstract: Biodiversity is mostly discussed at the level of species, but genetic variation within species may be as important as variation between species. It enables organisms to adapt to environmental changes. … Many other organisms must be genetically ‘prepared’ to meet environmental changes.
What is biodiversity explain different levels of biodiversity?
Levels of biodiversity. Biodiversity is usually explored at three levels – genetic diversity, species diversity and ecosystem diversity. These three levels work together to create the complexity of life on Earth.
Who is called the father of Indian ecology?
Ramdeo Misra is considered as the ‘Father of ecology’ in India.
How biodiversity is affected and endangered by human activities?
The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
Which country has the most biodiversity?
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.
