Answer 1

Answer: (B), (D)

The correct options are
B increase in photosynthesis of plants
D abundance of desert plants

An increase in content of carbon dioxide in an environment will not cause increase in photosynthesis of plants and abundance of desert plants.

Carbon dioxide is a greenhouse gas, so it traps the heat radiation and causes greenhouse effect.

Increase in concentration of green house gas will result in increase in average temperature of the earth. Thus it causes global warming.
