Question

Less carbon dioxide in an ecosystem means...

Answer 1

Explanation:

• When carbon dioxide concentrations drop, Earth cools, some water vapor falls out of the atmosphere, and the greenhouse warming caused by water vapour drops.

• At the same time global average temperatures are rising as a result of heat trapped by the additional CO2 and increased water vapor concentration.

Answer 2

Answer:

Land ecosystems currently play a key role in mitigating climate change. The more carbon dioxide (CO2) plants and trees absorb during photosynthesis, the process they use to make food, the less CO2 remains trapped in the atmosphere, where it can cause temperatures to rise.
