47. The resources which are obtained from bio sphere and have life are ____:
[A] Potential resources
[B] Biotic resources
[C] Abiotic resources
[D] Renewable resources
Show Answer
Correct Answer: B [Biotic resources]
Notes:
Biotic resources describe living or once living resources of a community; for example organisms, such as plants and animals wood, alkaloids, latex obtained from plant are also biotic resources. They are obtained from the biosphere and have life. The resources which are composed of non-living things are called Abiotic Resources. For example, water, minerals, metals, wind, solar energy etc.
48. Which of the following is not a particulate pollutant?
[A] Ozone
[B] Smoke
[C] Dust
[D] Soot
Show Answer
Correct Answer: A [Ozone]
Notes:
Particulate matter (PM) is a complex mixture of extremely small particles and liquid droplets that get into the air. This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets. Ozone is created in the atmosphere when the sun’s rays split oxygen molecules into single atoms. These atoms combine with nearby oxygen to form a three-oxygen molecule, called ozone.
49. Solar energy is converted into chemical energy during ____:
[A] Photosynthesis
[B] Combustion
[C] Transition
[D] Fusion
Show Answer
Correct Answer: A [Photosynthesis]
Notes:
Photosynthesis in plants converts radiant energy from the sun into chemical energy in the form of glucose (sugar) using electrons and protons from water. Plants take in water, carbon dioxide, and sunlight and turn them into glucose and oxygen. Water (6H2O) + Carbon Dioxide (6CO2) + Sunlight (Radiant Energy) = Glucose (C6H12O6) + Oxygen (6O2).
50. ‘Mylo’ is an un-leather fabric and a very sustainable product. It is made from which of the following organic material?
[A] Mushroom
[B] Bamboo
[C] Eucalyptus
[D] Coconut
Show Answer
Correct Answer: A [Mushroom]
Notes:
Mylo is a leather-like material made from mycelium, the underground root structure of mushrooms. Mylo is a sustainable alternative to leather because it can be grown without polluting substances. It is also more sustainable than synthetic leathers, which are usually made from petroleum-derived inputs.
Mylo is grown in a controlled indoor environment. The growing process is designed to be low impact and takes less than two weeks. It emits fewer greenhouse gases and uses less water and resources than animal-based leather.
Mylo is 80% bio-based and is completely biodegradable and compostable. However, when extra durability is needed, the mushroom leather is reinforced with polyurethane, which decreases its biodegradability.
