The splitting in of oxygen to form water. At the end of the chain, electrons are transferred to molecular oxygen,which splits in half and takes up H plus to form water.
Humans get there energy primarily from glucose I believe. We break down glucose to get ATP (Adenosine Triphosphate) which is then used to supply energy to our cells in order to function.
An autotroph is an example of a producer, something that builds its own nutrients from molecules such as carbon dioxide and water. In this case, the correct answer is d. A hawthorne tree uses the process of photosynthesis to produce nutrients such as simple sugars which can then be used to build organic molecules inside the plant to fuel respiration and other biochemical processes.
The light-independent reactions occur in the storm of the chloroplast<span>. The light- independent reactions are "independent" from light so they can happen else where. The light-dependent reactions happen in the thylakoid membrane of the chloroplast where the light is absorbed, and the reactions depend on the light.</span>
