The species of plants that plays a vital role in controlling the relative abundance of other species in a community is called
1 Exotic species
2 Keystone ospecies
3 Alien species
4 Endemic species
Explanation:
A keystone species are important providers of shelter and habitats for other species. - Keystone species are those which have an extremely high impact on a particular ecosystem relative to its population. - Exotic species are organisms that have been introduce into an area outside their normal distribution. - An alien species is an animal or plant that is introduced by humans, either accidentally or intentionally into places outside its natural range. Endemic species are those that live in a limited area.

Among 'The Evil Quartet', which one is considered the most important cause driving extinction of species?
1 Co-extinctions
2 Habitat loss and fragmentation
3 Over exploitation for economic gain
4 Alien species invasions
Explanation:
The Evil quartet of biodiversity loss is a concept that describes the reason that causes extinction of species loss of habitat. Extinction of species continuously and introduction of exotic species is the main reason of biodiversity loss. - Loss of habitat - when a natural habitat is not capable of supporting species that are native to it is called loss of habitat.

In our biosphere, the most important and vast area is covered by hydrosphere. Hydrosphere has
1 1.4 billion cubic $\mathrm{km}$ of water
2 1.4 million cubic $\mathrm{km}$ of water
3 2.5 billion cubic $\mathrm{km}$ of water
4 1.5 billion cubic $\mathrm{km}$ of water
Explanation:
Water is the most abundant substance at the surface of earth. About 1.4 billion cubic $\mathrm{km}$. - It has been estimated that 1,386 million cubic kilometers or $333,000,000$ cubic miles of water are present on the earth. This water is in liquid and frozen forms present in ground water, oceans, lakes and streams. Salt water accounts for $97.5 \%$ where as fresh water accounts for only $2.5 \%$.

A few organisms can tolerate and thrive in a wide range at temperatures. They are known as:
1 Eurythermal
2 Stenohaline
3 Stenothermal
4 Euryhaline
Explanation:
Some organism can tolerate a wide range of temperatures and thrive, they are known as eurythermal such as most birds and mammals and Artemisia. - Stenohaline spices are those organisms that can survive within a narrow of salinity the organism which can only tolerate narrow range of temperature are called stenothermal. - Euryhaline organisms are able adapt to a wide range of salinities.
