2 The wild areas will be safe for man and domestic animals
3 Its gene pool will be lost forever
4 The populations of beautiful animals like dears will get stabilized.
Explanation:
If the Bengal tiger becomes extinct, its gene pool will be lost forever. A gene pool refers to the combination of all the genes present in a reproducing population or species. Determining the gene pool is important in analyzing the genetic diversity of a population. The variety of genes in the gene pool can be quantified within a population.

One of endangered species of Indian medicinal plants is that of:-
1 Nepenthes
2 Podophyllum
3 Ocimum
4 Garlic
Explanation:
One of endangered species of Indian medicinal plant is that of podophyllum. Podophyllum peletatum is an herbaceous perennial plant in the family berberidaceae. It is cuide spread across most of the eastern united state. - Endangered species are species of animals or plants that are in danger of extinction. Deforestation has drastically reduced the population of medicinal and aromatic plants as their habitats have destroyed, e.g., various orchid species, podophyllum hexandrum, Atropa acuminate, skimmia onquetilia etc. IUCN report aound $50-80$ thousand flowering plant species are used in medicinal purposes.

Which one of the following became an endangered species as result of extinction of Raphus cucullatus?
1 Sideroxylon grandiflorum
2 Chrysanthemum
3 Cinchona
4 Bacillus thuringiensis
Explanation:
Sideroxylon grandiflorum Also known as tambalacoque or dodo tree, is a long-lived tree in the family Sapotaceae, endemic to Mauritius. It is valued for its timber. The Sideroxylon grandiflorum fruit is analogous to the peach. Chrysanthemum- Chrysanthemums, sometimes called mums or chrysanths, are flowering plants of the genus chrysanthemum in the family Asteraceae. They are native to East Asia and Northeastern Europe. Countless horticulture varieties and cultivars exist. Cinchona- Cinchona is a genus of flowering plants in the Family Rubiaceae containing at least 23 species of trees and shrubs. All are native to the tropical Andean forests of Western South America. Bacillus thuringiensis- (Bt) is a species of bacteria that lives in soil. It makes proteins that are toxic to some insects when eaten, but not others. They are protein not toxic to humans because, like all mammals, we cannot active them. Bt is not toxic to non-target wildlife.

Which of the following is the most important cause of animals and plants being driven to extinction
1 Co- extinctions
2 Over-exploitation
3 Alien species invasion
4 Habitat loss and fragmentation
Explanation:
Habitat loss is the important reason for the extinction in plants and animals. It is mostly in the tropical rainforest is now reduced to less than $5 \%$ from $15 \%$. - Habitat loss and fragmentation is the most important cause driving animals and plants to extinction. When large habitats are broken into small fragments due to various human activities, mammals and birds requiring large territories and certain animals with migratory habitats are badly affected leading to population declines.
