[#1] Ozone shield is component of
Correct Answer
(B) Stratosphere
Explanation
Solution: Ozone shield is component of Stratosphere. The stratosphere is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. The stratosphere is an atmospheric layer composed of stratified temperature layers, with the warm layers of air high in the sky and the cool layers of air in the low sky, close to the planetary surface of the Earth.
[#2] Lichens indicate pollution of
Correct Answer
(B) SO 2
Explanation
Solution: Lichens indicate pollution of SO 2 . A lichen is a composite organism that emerges from algae or cyanobacteria living among the filaments of fungi in a mutually beneficial symbiotic relationship. The fungi benefit from the carbohydrates produced by the algae or cyanobacteria via photosynthesis. Many lichens are very sensitive to environmental disturbances and can be used to cheaply assess air pollution, ozone depletion and metal contamination. The sensitivity of a lichen to air pollution is directly related to the energy needs of the mycobiont, so the stronger the dependency of the mycobiont on the photobiont, the more sensitive the lichen is to air pollution.
[#3] The geothermal energy utilises potential of
Correct Answer
(B) Temperature underneath the earth surface
Explanation
Solution: The geothermal energy utilizes potential of Temperature underneath the earth's surface. Geothermal energy is the heat produced deep in the Earth's core. Geothermal energy is a clean, renewable resource that can be harnessed for use as heat and electricity. Geothermal is used for heating baths and swimming pools, as well as for space and greenhouse heating. Other applications are industrial uses utilizing heat, aquaculture pond heating, agricultural drying, cooling and snow melting.
[#4] Biosphere is
Correct Answer
(A) In which individuals interact with each other
(E) Area occupied by living beings
Explanation
Solution: The biosphere is in which individuals interact with each other. The biosphere, also known as the ecosphere is the worldwide sum of all ecosystems. The biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, cryosphere, hydrosphere and atmosphere.
[#5] The most favoured habitat of plant is called
Correct Answer
(D) Microhabitat
Explanation
Solution: The most favoured habitat of plants is called Microhabitat. A microhabitat is a small area which differs somehow from the surrounding habitat. A habitat is an environment where an organism lives throughout the year or for shorter periods to find a mate. The habitat contains all an animal needs to survive such as food and shelter.
