Question

photosynthesis
inputs
outputs
the energy flow through living systems begins with sunlight and photosynthesis. an incomplete diagram of the process of photosynthesis is provided. what is the missing component that correctly replaces the question mark to complete the diagram?
water
oxygen
glucose
soil nutrients

Explanation:

The process of photosynthesis in plants requires inputs of sunlight, carbon dioxide, and water to produce outputs of glucose (energy - storing molecule) and oxygen. The diagram shows "Sunlight" as one input, and we need to identify the other input. Among the options, water is an essential input for photosynthesis (the equation is \(6CO_2 + 6H_2O+\text{light energy}
ightarrow C_6H_{12}O_6 + 6O_2\)). Oxygen and glucose are outputs, and soil nutrients are not direct inputs for the photosynthesis process itself.

Answer:

A. Water
