Question

Which of the following is not a possible effect of rising carbon dioxide levels on plants?

Answer 1

I think the correct answer from the choices listed above is option B. Plant mortality is not a possible effect of rising carbon dioxide levels on plants. This value is a fixed value and cannot be affected by changes in the carbon dioxide level.

Answer 2

Answer:

increased plant mortality

Explanation:

The rise of carbon dioxide in the atmosphere  will definitely bring about increased in photosynthesis.

Photosynthesis in plants is a process whereby green plant produces nutrient in the present of sunlight from carbon dioxide and water. Photosynthesis is a necessity for plants to supply nutrient to the plants . The chemical equation for photosynthesis  can be represented as follows:

6CO2 + 6H2O sunlight → C6H1206 + 6O2

Photosynthesis converts light energy into chemical energy. Green plants in the presence of sunlight uses CO2 and H2O to produce food. Increase carbon dioxide will definitely increase crop productivity and plant growth. The more the carbon dioxide and water in the presence of sunlight  nutrient are added to the plant.

Plant will definitely not die because of rise in CO2.
