question 2 (10 points)
food producers do not need ______ to
make sugar.
a water
b carbon dioxide
c nitrogen dioxide
d light

Explanation:

Food producers (like plants) make sugar via photosynthesis. The photosynthesis equation is \(6CO_2 + 6H_2O \xrightarrow[\text{Chlorophyll}]{\text{Light}} C_6H_{12}O_6 + 6O_2\). So they need water, carbon dioxide, and light. Nitrogen dioxide is not required for sugar production.

Answer:

c. Nitrogen dioxide
