Question

If concentration in CO₂ increases continuously in the environment, what will be its effect?

Options

• Ozone depletion

• Greenhouse effect

• Increase in photorespiration

• Suffocation

Answer 1

Greenhouse effect

Explanation:

An increase in carbon dioxide (CO₂) concentration in the environment enhances the greenhouse effect, where CO₂ and other greenhouse gases trap heat in the Earth’s atmosphere. This leads to global warming, causing a rise in Earth’s average temperature, melting of glaciers, flooding of coastal areas, and changes in climate patterns. CO₂ is not directly responsible for ozone depletion, an increase in photorespiration, or suffocation, but its rise mainly contributes to the greenhouse effect and global warming.
