  • They obtain their nutrients mostly from the air.

Additional Information

  • Bioindicators:
    • Bioindicators are living organisms which are utilized to screen the health of the natural ecosystem in the environment.

In this question, a passage and a statement related to it have been given. Read carefully the verse and review the statement based on it. Delhi, which is one of India's capital an d one of the largest cities in the world, is undergoing severe crisis, due to its high level of urbanization, increasing population and high levels of pollution. Studies have proven that Are the biggest factors of pollution used for industrial and domestic use? And due to their use, people here emit large quantities of nitrogen oxides (NOx), ozone (O3), black carbon (BC) and microorganisms (PM). According to the 2015 Global Burden of Disease report, there were 1.09 million deaths due to PM 2.5 in India. Air pollution was included as one of the 10 biggest threats to health. According to the World Health Organization, 37 cities of India are among 100 worst polluted cities in the world, where PM10 was found to be the highest ever. For the production of ozone, together with sunlight and heat, nitrogen oxides (NOx) and organic compounds (VOCs) are needed simultaneously. Therefore, in the summer months, ozone is produced in large quantities in the cities. Statement: Air pollution is one of the top 10 factors affecting health in India. Select the most suitable from the following options A-statement is absolutely true B-statement is probably true C-statement can not be reviewed D-statement is completely false
Read the paragraph and answer the question that follows: Incessant combustion of fossil fuels emits toxic gases, polluting the air; urbanization results in deforestation and hence poor air quality; littering of plastic waste damages the productivity of soil and pollutes water bodies. Environmental pollution results in more serious consequences like – global warming, unexpected climatic changes, depletion of natural resources, species depletion, and various other adverse effects leading to a lowered sustainability of life on earth. Another prime contributor to the pollution of the environment is plastic pollution. Plastic bags those are not disposed of properly, reach the soil and water bodies, polluting them and damaging dependent lives. Being non-bio degradable plastic lingers around for years, rendering them useless. What is the prime contributor to pollution?

In the question given below,three paragraphs are given, which arejumbled. Find the correct sequence ofthese paragraphs so that they form ameaningful passage.
A. Climate change is warming the ocean,but its warming land faster and thatsreally bad news for air quality all overthe world, says a new University ofCalifornia, Riverside study. The study,published February 4 in Nature ClimateChange, shows that the contrast inwarming between the continents andsea, called the land-sea warmingcontrast, drives an increasedconcentration of aerosols in theatmosphere that cause airpollution. Aerosols affect the climatesystem, including disturbances to thewater cycle, as well as human health.They also cause smog and other kinds ofair pollution that can lead to healthproblems for people, animals, andplants.
B. To determine this, the researchersran simulations of climate change undertwo scenarios. The first assumed abusiness-as-usual warming model, inwhich warming proceeds at a constant,upward rate. The second model probeda scenario in which the land warmed lessthan expected. In the business-as-usualscenario, enhanced land warmingincreased continental aridity and,subsequently, the concentration ofaerosols that leads to more air pollution.
C. A robust response to an increase ingreenhouse gases is that the land isgoing to warm faster than the ocean.This enhanced land warming is alsoassociated with increased continental
aridity. The increase in aridity leads todecreased low cloud cover and less rain,which is the main way that aerosols areremoved from the atmosphere.
