alters and interferes with the timing of necessary biological activities

A

light pollution

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.

23
Q

Three ways water is available to plants

A

atmospheric moisture, precipitation, soil water

24
Q

air in motion

25
can directly contaminate the surface of bodies of water and soil
air pollution
26
It is an exothermic factor caused due to the chemical process of combustion, releasing heat and light.
fire
27
It is mostly man-made and some-times develops naturally due to the friction between the tree surfaces.
fire
28
It is not a kind of pollution but it is a problem that destroys our ecology that uses fire as its agent.
forest fire
29
two ways forest fire can start
naturally caused, human caused
