Multiple Choice

In photosynthesis, what are the inputs and outputs in terms of energy and matter?

Photosynthesis converts light energy into chemical energy stored in glucose, using matter from the environment. Light energy powers the reactions that combine carbon dioxide from the air with water from the plant to make glucose, and oxygen is released as a byproduct. So the inputs are light energy, carbon dioxide, and water; the outputs are glucose and oxygen. The other options miss either the glucose output or misstate the inputs, so this choice best reflects how energy and matter flow through photosynthesis.
