How can we save coral reefs ?

  1. Use dynamite in fishing

  2. Destroy coral reefs for a good harvest of fish

  3. Use artificial reefs out of old tires

  4. Avoid dynamite fishing
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Dynamite fishing destroys coral reef ecosystems by blasting coral formations, which take decades to recover. Avoiding destructive fishing practices is essential for coral conservation. Using artificial reefs (option C) can help but doesn't address the root problem of destruction, and intentionally destroying reefs (B) or using dynamite (A) are actively harmful practices.

A,C Correct answer
Explanation

Coral reefs provide shelter for fish species and protect coastlines from waves and currents. They do not consume ocean resources or feed on algae.

Multiple choice general knowledge science & technology
  1. Things to do in preserving wildlife

  1. (a) controlling natural predators

  2. (b) providing suitable habitat

  3. (c) stopping all hunting

  4. (d) leaving everything alone, letting nature take its course
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Providing suitable habitat is fundamental to wildlife preservation because animals need food, water, shelter, and space to survive and reproduce. Controlling natural predators disrupts ecosystems, stopping all hunting is often impractical, and leaving everything alone doesn't help when habitats are already degraded.

Multiple choice

One of the most important functions of botanial gardens is that

  1. they allow ex-situ conservation of germless

  2. they provide the natural habitat for wildllil

  3. one can observe tropical plants there.

  4. they provide a beautiful area for recreatia
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Botanical gardens serve as ex-situ conservation sites, maintaining living collections of plant species outside their natural habitats. This preserves genetic diversity (germplasm) for research, education, and potential reintroduction. They do not provide natural habitat for wild plants (that's in-situ conservation), and while they may have tropical plants and recreational areas, these are not their 'most important' scientific function.

The wildlife conservation projects and programs

To promote wildlife awareness among the people, the Indian government has started various natural projects and programs such as Project Tiger, Nature Camps and Jungle Lodges. These projects not only help to preserve our natural heritage, but encourage eco-tourism as well. Project Tiger was formed in 1972 and launched on the 1st April 1973 at Corbett National Park. Till date, the project has been the most successful one in preserving the tiger population at Tiger Reserves in Bandhavgarh, Corbett, Pench, Ranthambhore, Kanha, Bandipur, Panna, Dudhwa, Sunderbans, Manas and Sariska. All these reserves act as Conservation Centers for tigers in India. Besides, there is the Gir National Park, the only habitat for Asiatic lions in India. The Kaziranga Wildlife Sanctuary is Assam is renowned for protecting the endangered one-horned Rhinoceros. There's also Dachigam National Park, which conserves the Hangul or Kashmiri Stag. Project Elephant, a centrally sponsored scheme, was launched in February 1992 to provide financial and technical support to major elephant bearing states in India for protection of elephants, their habitats and corridors. The Project, involving 25 Elephant Reserves across the country, is being implemented in 13 States and Union Territories in India, namely, Andhra Pradesh, Arunachal Pradesh, Assam, Jharkhand, Karnataka, Kerala, Meghalaya, Nagaland, Orissa, Tamil Nadu, Uttaranchal, Uttar Pradesh and West Bengal.

Multiple choice

What is the modern use of sacred groves?

  1. Repository for various Ayurvedic medicines

  2. Reduce soil erosion

  3. Biodiversity hotspots

  4. Recharging aquifers
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In modern times, sacred groves have become biodiversity hotspots as various species seek refuge in the areas due to progressive habitat destruction and hunting. Sacred groves often contain plant and animal species that have become extinct in the neighbouring areas. They, therefore, harbour great genetic diversity.

Multiple choice

Viable material of endangered species can be preserved by

  1. gene bank

  2. gene library

  3. gene pool

  4. gene map
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Gene banks are a type of bio-repository, which preserve viable genetic material. For plants, this could be by freezing cuttings from the plant or stocking the seeds. For animals, this is freezing of sperms and eggs in zoological freezers until further need.

Multiple choice

In sito conservation of natural, genetic resources can be achieved by

  1. controlling the native habitat

  2. controlling air pollution

  3. restricted human interference in the biosphere

  4. establishing national parks and wild life sanctuaries
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In situ conservation means protecting species in their natural habitat. Establishing national parks and wildlife sanctuaries directly preserves native habitats and ecosystems. Controlling habitat or pollution are broader environmental measures, while restricting human interference is too vague - protected areas specifically achieve this through legal frameworks.
