B Correct answer
Explanation

Oxygen chlorine fumes of nitric acid are the air pollutants which caused photochemical oxidants. photochemical oxidants means the pollutants formed under influence of sunlight by complex photochemical reactions.

Multiple choice

Carbon monoxide is a pollutant because

  1. It reacts with O2

  2. In inhibits glycolysis

  3. Reacts with haemoglobin

  4. Makes nervous system inactive
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Carbon monoxide is the main air pollutant. It first reduces the oxygen carrying capacity of haemoglobin and then cause asphuxiation

Multiple choice

Aerosols reduce primary productivity by

  1. decreasing oxygen concentration in the atmosphere

  2. reducing photosynthesis

  3. competing with carbon dioxide

  4. being toxic to chloroplast

  5. -

C Correct answer
Explanation

Aerosols target carbon dioxide and combines with it easily. It makes carbon dioxide unavailable for photosynthesis, therby decreasing primary productivity.
