Cellular Respiration
Explanation:
For something to be living it doesn't need to be a cell or do photosynthesis. Cellular Respiration is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities
I'm not sure what YOU already know about photosynthesis and cellular respiration.... however, you SHOULD know that the two are beautifully linked to one another!
Photosynthesis equation:
6CO2+6H2O -> C6H12O6+H2O
Cellular respiration
C6H12O6+H2O -> 6CO2+6H2O
Notice something? The substrates of one equation are the products of the other! We rely on plants for their photosynthetic reactions - and plants benefit from us (not really because there is already a TON of CO2 in the atmosphere) from our cellular respiration
***we like their oxygen and they like our carbon dioxide!
:) I hope that helps! Let me know if you need any more elaboration!
The spinal cord and the brain make up the central nervous system, and spinal cord nerves carry most messages between the brain and the rest of the body.
The vagus nerve carries the signal from the brain to the heart.
