Figure 8–4 In order for a candle to burn, oxygen needs to be present. Excess amounts of
carbon dioxide puts out flames. Consider the two sealed jars in Figure 8-4, which
are placed in a greenhouse, and choose the most correct statement
1.) Carbon dioxide produced by jar A allows the candle to remain burning long than jar B.
2.) Oxygen produced by the plan in jar A during cellular respiration will allow the candle to
remain burning for longer thanjar B.
3.) A and B are correct
4.) Oxygen produced by the plant during photosynthesis in jar A will allow the candle to
remain burning for longer than jar B
