Question

An increase in carbon dioxide content in the atmosphere would not cause

Options

• more heat to be retained by the environment

• increase in photosynthesis in plants

• global warming

• the abundance of desert plants

Answer 1

the abundance of desert plants

Explanation:

Since carbon dioxide is a greenhouse gas, an increase in its concentration will lead to the retention of more heat by the environment. The increased level of carbon dioxide and temperature will increase the rate of photosynthesis in plants. The retention of heat due to increased CO₂ concentration will cause an increase in average global temperature, resulting in global farming. Since the increase in CO₂ concentration does not create xerophytic conditions, thus there is no increase in the abundance of desert plants.
