What percentage of the land area should remain covered by forests to maintain ecological balance?

10%
5%
33%
None

Correct Answer

A. 33%

Explanation

Maintaining a balance in the ecosystem requires a significant portion of land to be covered by forests. Forests play a crucial role in preserving biodiversity, regulating climate, and providing habitats for various species. A percentage as high as 33% ensures the preservation of essential ecological processes and supports the sustainability of ecosystems. This allows for the conservation of wildlife, prevention of soil erosion, and regulation of water cycles, among other benefits. A lower percentage would likely result in a loss of biodiversity and disruption of ecosystem services, while a higher percentage may not be feasible or necessary for maintaining ecological balance.

What structural modification of oxygen is an air pollutant in the lower atmosphere but beneficial in the upper atmosphere?

Correct Answer
ozone,Ozone

Explanation
Ozone is a structural modification of oxygen that is considered an air pollutant in the lower atmosphere because it contributes to the formation of smog and can be harmful to human health. However, in the upper atmosphere, ozone is beneficial as it forms a protective layer, known as the ozone layer, which absorbs the majority of the sun's harmful ultraviolet (UV) radiation, preventing it from reaching the Earth's surface. This protective function of ozone is crucial for maintaining the overall balance of life on Earth.

Taj Mahal is threatened due to?

Sulphur dioxide
Carbondioxide
Carbon monoxide
Water vapour

Correct Answer

A. Sulphur dioxide

Explanation

Sulphur dioxide is a major threat to the Taj Mahal. It is primarily emitted from industries, vehicles, and burning of fossil fuels. When sulphur dioxide combines with moisture in the air, it forms sulphuric acid, which can cause corrosion and damage to the marble structure of the Taj Mahal. This acid rain also leads to the yellowing and blackening of the monument's pristine white surface. Therefore, the presence of sulphur dioxide poses a significant risk to the preservation and longevity of the Taj Mahal.

What environmental problem is the result of chemical reactions in the atmosphere that involve sulfur?

Deforestation
Acid rain
Holes in the Ozone layer
Smog

Correct Answer

A. Acid rain

Explanation

Chemical reactions in the atmosphere involving sulfur result in the environmental problem of acid rain. Acid rain is formed when sulfur dioxide and nitrogen oxides react with water, oxygen, and other chemicals in the atmosphere, forming sulfuric acid and nitric acid. These acids then fall to the ground in rain, snow, fog, or dry particles, causing harm to the environment by damaging forests, lakes, and buildings, and also posing risks to human health.

The most biologically diverse ecosystem on the land is:

Forests
Wet lands
Great plains
Deserts

Correct Answer

A. Forests

Explanation

Forests are the most biologically diverse ecosystem on land because they provide a wide range of habitats and niches for a variety of plant and animal species. The dense vegetation in forests supports a high number of species, including trees, shrubs, understory plants, insects, birds, mammals, and reptiles. Forests also have complex food webs and provide shelter, food, and breeding grounds for many organisms. The diverse array of species in forests contributes to the overall health and stability of the ecosystem, making them the most biologically diverse ecosystem on land.

A mountain lion

Correct Answer

A. A mirror

Explanation

The correct answer is a mirror. The question mentions that the picture frame was labeled as "The most dangerous species in the world." This implies that the answer should not be an actual dangerous species like a great white shark or a mountain lion. Instead, it is likely to be something that reflects back at the viewer, like a mirror.
