My favorite famous person is Donald Trump, because he is a successful businessman being one of the richest people in the world and the president of the United States of America which makes him a big inspiration for me. We are connected molecularly because matter can't be created nor destroyed so we have part of the same molecules within us
The ability for plants to do these two things is saving lives every single second if anyone is eating anything it is a product of photosynthesis because all of food sources straight back to plants being able to perform photosynthesis and convert light energy from the sun into ATP and food for the plant
My favorite autotroph is the Cherry Blossom or Sakura tree, it is a cool looking tree with the leaves/petals falling off almost constantly. Everyone is connected molecular to these trees because you have most likely eaten a product that these trees have created
The relationship between these things is that all of them have the ability to do cellular respiration but only one of them can do photosynthesis because of their chloroplasts. Sometimes these carbohydrates get transferred into organic acids or alcohol by microorganisms like yeast in a process called fermentation
Cellular respiration happens inside of an organism so I can be in the 1400's in an igloo and I will still have the ability to perform cellular respiration at any time I need
These plants take Carbon molecules and split them and reform into carbohydrates (water, oxygen, and carbon) they can also reform it into glucose. after they do these things as a part of photosynthesis there is a waste product (carbon monoxide) that is produced along with the oxygen we breathe
