Statement II: Fig wasp and fig tree exhibit a mutual relationship as the fig wasp completes its life cycle in the fig fruit and the fig fruit gets pollinated by the fig wasp. - An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

Environmental Pollution
When there is an unpleasant change in the surrounding that has harmful effects on plants and animals, it leads to environmental pollution. Pollution is the root cause of a substance - “pollutant”. We can have pollutants in solid, liquid, or gaseous forms. A substance becomes a pollutant when its concentration is greater than the natural abundance and this increase in concentration is either because of human activities or natural phenomena.
Effects of Environmental Pollution:
Some pollutants are scraped into the soil by human beings. This leads to air, water, and soil pollution. If the soil is polluted, the helpful or functional microorganisms in it will die and the fertility of the soil will vanish. The production of crops will diminish. If the soil is not fertile; it will have a harmful consequence on human society.
