Question

Increasing

Answer 1

Answer:

Increasing  carbon dioxide  concentration  increases the  rate of  photosynthesis  as carbon  dioxide (CO2) is a limiting factor.

Explanation:

Some limiting factors like carbon dioxide, temperature etc. influence the photosynthetic rate, which may end up reducing the potential amount of carbohydrate produced by photosynthesis. Carbon dioxide is important for this form of biosynthesis: it provides the inorganic carbon that is integrated into carbohydrate molecules.

The photosynthetic rate can be slowed by a decline in the concentration of available carbon dioxide.

6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen
