Question

through the process of
in a fern, the carbon atom in the
co₂ became a part of a glucose
molecule (c₆h₁₂o₆) in a fern.

Explanation:

Step1: Recall the process of photosynthesis

Photosynthesis is the process by which plants, including ferns, use light energy to convert carbon dioxide ($CO_2$) and water ($H_2O$) into glucose ($C_6H_{12}O_6$) and oxygen ($O_2$). The general equation for photosynthesis is

$$6CO_2 + 6H_2O+light\ energy ightarrow C_6H_{12}O_6 + 6O_2$$

. In this process, carbon atoms from $CO_2$ are incorporated into glucose.
