During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen.
Then Respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
Answer:
Plants experience the highest rate of cellular respiration
The process is called Peer-Reviewing. In Peer-Reviewing, scientists/academic peers "peer review" the work of a scientist to check for accuracy or any false information that might reduce the legitimacy of their study or change "how realistic/real" their study is.
p.s. This is also common sense because scientists make up an entire scientific community who base their scientific studies on consistency and accuracy.
There are 6 elements that are the most important. The acronym, CHNOPS, is an easy way to remember these.
C - Carbon
H - Hydrogen
N - Nitrogen
O - Oxygen
P - Phosphorous
S - Sulfur
