Animals and plants are very close in nature because the ______ animals breathe out
is used to by plants to produce their food and let out oxygen, and the _______
produced by plants is required for cellular respiration. - ANSWER-carbon dioxide,
oxygen
What is the difference between cellular respiration and breathing? - ANSWER-
cellular respiration is a chemical reaction happening 24/7 at the cellular level of an
organism, breathing is the mechanism that organisms use to get rid of the carbon
dioxide and bring fresh oxygen into their bodies
