17
Q

It is one of the easiest pollutions to clean up.

A

light pollution

18
Q

It is a public or private land area possessing an exceptional or distinguished quality of starry nights and nocturnal environment that is specifically protected for its scientific, natural, educational, cultural, heritage and/or public enjoyment.

A

IDA International Dark Sky Reserve

19
Q

It is one of the important factors which affect almost all the metabolic activities of an organism.

A

temperature

20
Q

Every physiological process in an organism requires an optimum temperature at which it shows the _________.

A

maximum metabolic rate

21
Q

It is any deviation from the natural temperature in a habitat and can range from elevated temperatures associated with industrial cooling activities to discharges of cold water into streams below large impoundments.

A

thermal pollution

22
Q

It is one of the most important climatic factors; affects vital processes of all living organisms.

A

water

23
Q

Three ways water is available to plants

A

atmospheric moisture, precipitation, soil water

24
Q

air in motion

A

wind

25
Q

can directly contaminate the surface of bodies of water and soil

A

air pollution

26
Q

It is an exothermic factor caused due to the chemical process of combustion, releasing heat and light.

A

fire

27
Q

It is mostly man-made and some-times develops naturally due to the friction between the tree surfaces.

A

fire

28
Q

It is not a kind of pollution but it is a problem that destroys our ecology that uses fire as its agent.

A

forest fire

29
Q

two ways forest fire can start

A

naturally caused, human caused
