Question

plants take in several inputs from their environment to carry out photosynthesis. list the three main inputs of photosynthesis and the two main outputs. then, explain in one sentence how these inputs and outputs help cycle matter and energy through an ecosystem.

Explanation:

The problem is about photosynthesis in plants, which falls under Biology (a subfield of Natural Science). The three main inputs of photosynthesis are carbon dioxide ($\ce{CO_2}$), water ($\ce{H_2O}$), and light energy. The two main outputs are glucose ($\ce{C_6H_{12}O_6}$) and oxygen ($\ce{O_2}$). These inputs and outputs help cycle matter and energy as plants use light energy to convert $\ce{CO_2}$ and $\ce{H_2O}$ into glucose (storing energy) and $\ce{O_2}$; then, other organisms consume glucose (releasing energy) and produce $\ce{CO_2}$ and $\ce{H_2O}$ through respiration, continuing the cycle.

of cycling: Plants use light energy to convert $\ce{CO_2}$ and $\ce{H_2O}$ into glucose (storing energy) and $\ce{O_2}$; other organisms consume glucose (releasing energy) and produce $\ce{CO_2}$ and $\ce{H_2O}$ via respiration, cycling matter and energy.

Answer:

Inputs of photosynthesis: Carbon dioxide ($\ce{CO_2}$), Water ($\ce{H_2O}$), Light energy.
Outputs of photosynthesis: Glucose ($\ce{C_6H_{12}O_6}$), Oxygen ($\ce{O_2}$).
