The molecule produced by light reactions in plants and used by some bacteria for cellular respiration is oxygen. Photosynthesis occurs only in the light, whereas cellular respiration occurs in both the light and the dark. Complex organic molecules release energy during cellular respiration, but they store energy during photosynthesis.
The majority of autotrophs, or organisms that do not rely on external food sources, obtain the majority of their energy from light reactions. These organisms are known as photoautotrophs. When light is present, chemical reactions known as "light reactions" occur. Photosynthesis is the plant-based light-induced reaction.
This is the process of converting light energy into chemical energy. The sun's light energy is converted into the compounds ATP and NADPH during this process (nicotinamide adenine dinucleotide phosphate).

Answer:
If a group of living organisms is unable to adapt to changing conditions with the earth's system, it shall face extinction.
Explanation:
As time goes by, the earth's systems keep changing, either negatively or positively.
If the earth's temperature decreases then living organisms shall adapt to surviving in cold conditions, they shall for instance grow heavy fur cover on their skin to cover them from the cold.
Those that fail to adapt to the cold conditions shall face extinction by being overpowered by cold related complications.
The rapid breathing rate is the body's way of trying to increase oxygen or lower carbon dioxide levels in the blood.
They cannot live without water
