D. Proteins are composed of amino acids and determines all the structures and functions of the organism.
Explanation:
Carbon dioxide is needed for photosynthesis, but oxygen is needed for cellular respiration. Assuming there is still oxygen then the plants will produce carbon dioxide and some of it will be reabsorbed by photosynthesis during daylight. However, ultimately there wouldn’t be enough carbon dioxide for the plants to grow and they will start to die. Some plants have evolved a C4C4 photosynthesis pathway so they only require a small amount of CO2CO2 to survive, however they do still require more than zero CO2CO2.
So basically you killed off all the plants and all the other non-microbial life died of starvation shortly afterward.

Cells get energy for their functioning through sunlight and other organic food molecules. ATP is a good example of energy pathways through photosynthesis.
The answer is B. They are both made up of subatomic particles.
