Biodiversity: The variety of all living organisms and genetic variation within ecosystems and across the planet.
Explanation
Biodiversity includes species diversity (number of different species), genetic diversity (variation within species), and ecosystem diversity (variety of ecosystems). High biodiversity ecosystems like rainforests are more stable and productive. Species extinction reduces biodiversity and weakens ecosystems. India is one of the most biodiverse countries, home to tigers, elephants, and millions of plant species. Habitat destruction is the main threat to biodiversity. Conservation efforts protect endangered species and preserve ecosystems. Biodiversity is essential for human survival, providing food, medicine, and ecosystem services.
Example
A rainforest has high biodiversity with thousands of plant and animal species. A desert has lower biodiversity with fewer species adapted to dry conditions.
Frequently Asked Questions
Why is biodiversity important?
Biodiversity ensures ecosystem stability, provides resources for medicine and food, and makes ecosystems resilient to environmental changes.
What is an endangered species?
An endangered species is one that is at high risk of extinction due to habitat loss, hunting, or disease.
