Question 7 of 9

What would happen if photosynthesis could no longer occur on the planet?
A. Remaining oxygen would be used up.
о B. Less carbon dioxide would be produced.
C. Less energy would come from the Sun.
OD. Food chains would become stable.

Answer 1

If photosynthesis could no longer occur on the planet, the consequences would include a decrease in available oxygen, an increase in atmospheric CO2 levels, and a destabilization of food chains.

Step-by-step explanation:

If photosynthesis could no longer occur on the planet, several consequences would follow. Firstly, the remaining oxygen in the atmosphere would be gradually used up, leading to a decrease in available oxygen for organisms to breathe. Secondly, with photosynthesis no longer taking place, less carbon dioxide would be absorbed from the atmosphere by plants, potentially leading to an increase in atmospheric CO2 levels. Finally, since photosynthesis is the primary source of energy for most ecosystems, the amount of energy flowing through food chains would significantly decrease, leading to a destabilization of these chains.
