Class 12 Science - What are biodiversity and its importance

Class 12 biology biodiversity and its importance


Biodiversity, often known as biological diversity, refers to the diversity of living things on the planet. It explains the degree to which life varies. Microorganisms, plants, animals, and ecosystems such as coral reefs, forests, rainforests, and deserts are all examples of biological diversity.

Importance of Biodiversity

Biodiversity benefits the Earth in a multitude of ways. The following are some examples:

Ecological stability is provided through biodiversity. Within an ecosystem, each species serves a certain purpose. Organisms capture and store energy from the sun (the Earth's sole source of energy), produce organic material and destroy organic stuff. Biodiversity aids the water and nutrient cycle throughout the ecosystem, reduces soil erosion, and aids in the fixation of atmospheric gases so that they can be used by various organisms. Biodiversity regulates the climate.

A healthy ecosystem supports the production of products and services that humans require to survive. These include soil fertility, plant pollinators, predators, waste decomposition, air and water purification, climate stabilisation and moderation, and reduced flooding, drought, and other environmental disasters.

Human economic benefits: Biodiversity is a crucial resource for all humans in their daily lives. Food, pharmaceutical, medicinal, and cosmetic items all benefit from biodiversity.

Crops, cattle, forestry, and fish are all examples of food products.

Many wild plant species have been used for therapeutic purposes since the dawn of time. Quinine, for example (Used to treat malaria). Quinine comes from the bark of the Amazonian Cinchona tree, while morphine comes from the poppy plant (pain alleviation), and so forth. More than 70% of promising anti-cancer medications come from tropical rainforest plants, according to the National Cancer Institute of the United States. Animals may also play a significant role in the acquisition of medications.

Biodiversity provides raw materials for numerous sectors, including clothing fibres, shelter, and warmth.

Why is Hindi Day celebrated on 14 September?

Why is Hindi Day celebrated on 14 September? After independence, the Government of India set a goal to give an ideal form to the mother tongue of the country and set a target for grammar and orthography using the Devanagari script to bring standardization in writing. Subsequently, on September 14, 1949, the Constituent Assembly decided by a vote that Hindi would be the official language of India. To propagate the importance of this decision and to spread Hindi in every region, India is celebrating Hindi Day every year from 1953 to 14 September, at the request of Rashtrabhasha Prachar Samiti, Wardha. Apart from this, 14 September is also the birthday of Rajendra Singh, who worked tirelessly to make Hindi the official language of India. Hindi Day is observed every year on 14 September to mark the importance of the Hindi language in the country. The Hindi language is one of the oldest languages, which derives most of its academic vocabulary from the Sanskrit language written in the Deva

Magnetic and non-magnetic material Class 6 Science

Magnetic and non-magnetic material  Class 6 Science A magnet is a substance that is drawn to certain magnetic materials like iron, cobalt, and nickel. Magnets have the ability to draw iron to them. Natural magnets are rocks that naturally draw iron. Non-magnetic materials include things like wood, rubber, coins, feathers, leather, etc. that are not drawn to iron. Magnet characteristics It pulls magnetic materials, such as iron. The magnet's two ends are referred to as its poles. The magnet's diametrically opposed poles are drawn together. Heating, hammering, or dropping causes it to lose its characteristics. On the basis of properties types of Magnets Temporary magnets are those magnets that are magnetic for only a little duration. Typically, iron, cobalt, or nickel are used to make them. When they are close to the powerful magnet, they act like a magnet. When they are yanked away from the powerful magnet, they stop being magnetic. Permanent magnets are magnets that have magne
