Answer:
The cells of living things are made mainly of four elements: carbon, hydrogen, oxygen and nitrogen. They make up 96% of the atoms that are in living things, so they would be considered major chemicals. However, depending on how you define major, other elements that only make up a few percent of cells can top the list.

Answer:
B) They do not get enough oxygen, and die.
Explanation:
They loose oxygen due to the algae. The algae bloom uses up all the O2 in the plant structures
.
Answer:
The ATPs produced during Chemeiosmosis, in the chloroplast is needed during Calvin cycle to fix carbon for production of CHO, protein and fats during conversion of 3C-glyceride phosphate(GP) to 2C- triose phosphate.(TP) .
The ATPs is needed for this reduction to take place in the presence of NADPH(which is oxdized to NADP).
Therefore, if the final electron acceptor is removed, there will be no electron transport chains which generated the PMF, for pumping H+ across into the thylakoid membrane of the chloroplast, to generate the electrochemical gradients, needed for the energy for ATPase synthase enzymes,to synthesize ATPs production.
Therefore, the removal of the electron acceptor (oxygen) leads to stoppage of electron transport chain, and hence loss of ATP s, and therefore, no Carbon fixation as CHO, or protein, or fats.
