Which component of the earth’s atmosphere is decreased due to photosynthesis? ozone
oxygen
hydrogen peroxide
carbon dioxide

Carbon Dioxide

Explanation:

Let's see the reaction of Photosynthesis

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Where carbon dioxide and water are reactants and glucose and oxygen are products which means CO₂ and H₂O are taken from the environment and glucose is supplied to plants while oxygen is supplied back to the environment.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.

magnesium is an electrolyte injection commonly used to treat low magnesium levels in your blood. it is also used to prevent or control seizures in women with preeclampsia or eclampsia.
