Which of the following statements best describes the carbon atoms present in a seed-eating bird?
A) They were incorporated into organic molecules by plants.
B) They were processed into sugars through photosynthesis.
C) They are ultimately derived from carbon dioxide.
D) They were incorporated into organic molecules by plants, and they are ultimately derived from carbon dioxide.
E) They were incorporated into organic molecules by plants, they were processed into sugars through photosynthesis, and they are ultimately derived from carbon dioxide.

Question

Quizplus · Accepted Answer

The carbon atoms in a seed-eating bird come from the seeds it eats, which in turn get their carbon from plants. Plants incorporate carbon into organic molecules, process it into sugars through photosynthesis, and ultimately derive it from carbon dioxide in the atmosphere. Therefore, all the processes described in E contribute to the presence of carbon atoms in a seed-eating bird.
