Step-by-step explanation:
B: The plants take the CO₂ and turns it into O (oxygen)
F: The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. respiration takes place in the mitochondria of the cell in the presence of oxygen
E: Most organisms become fossils when they're changed through various other means. This process which is called carbonization, or distillation yields a detailed carbon impression of the dead organism in sedimentary rock
