Eutrophication is associated with ______ pollution.

Acid rain reduces ______. Find the odd one out.

The increase in the concentration of various toxic substances along the food chain is called ______.

Assertion (A): The amount of carbon dioxide in the atmosphere remained constant in the past.

Reason (R): Plants absorbed carbon dioxide during photosynthesis and give out oxygen, balancing the amount of carbon dioxide produced by natural processes.

Assertion (A): Global warming is primarily caused by an increase in carbon dioxide in the atmosphere.

Reason (R): The destruction of forests and vegetation has reduced the environment's capacity to absorb carbon dioxide, leading to its rapid accumulation in the atmosphere.

Assertion (A): Acid rain increases the fertility of the soil.

Reason (R): Acid rain is formed when sulphur dioxide and nitrogen dioxide react with rainwater to form sulphuric acid and nitric acid.

Assertion (A): Smog is responsible for several health problems like asthma, chronic bronchitis, and lung infections.

Reason (R): Smog is formed when sunlight reacts with smoke produced from the burning of wood for cooking in rural areas, creating a combination of smoke and fog.
