Study Notes
Biodiversity in India
- India is one of the most diverse nations in the world, ranking ninth in terms of plant species richness.
- Two of the world's 25 biodiversity hotspots are found in India.
- India is the origin of important crop species such as pigeon pea, eggplant, cucumber, cotton, and sesame.
- It is also a centre of various domesticated species like millets, cereals, legumes, vegetables, medicinal and aromatic crops.
Ecosystem
- An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
- Ecosystems contain biotic or living parts, as well as abiotic factors, or non-living parts.
- Biotic factors include plants, animals, and other organisms.
- Abiotic factors include rocks, temperature, and humidity.
- Every factor in an ecosystem depends on every other factor, either directly or indirectly.
Importance of Biodiversity
- Biodiversity and its maintenance are very important for sustaining life on earth.
- Ecological stability: diverse ecosystems are more productive and can withstand environmental stress.
- Economic importance: biodiversity is a reservoir of resources for the manufacture of food, cosmetic products, and pharmaceuticals.
- Ethical importance: all species have a right to exist, and humans should not cause their voluntary extinction.
Types of Biodiversity
- There are three different types of biodiversity: genetic, species, and ecological.
- Species diversity: refers to the variety of different types of species found in a particular area.
- Genetic diversity: refers to the variations among the genetic resources of organisms.
- Ecological diversity: refers to the diversity observed among different ecosystems in a region.
