Answer:
Plants convert CO2 to O2.
Explanation:
Photosynthesis turns CO2 and H2O Into C6H12O6 and O2, glucose and oxygen. Most animals need oxygen to survive.
The consumed food first need to be physically broken and after that chemically. The energy stored in food (food contains carbohydrates, fats, proteins, water, vitamins, and minerals) is released when chemical bonds of molecules in food are broken in metabolic processes such as cellular respiration. Cellular respiration might be aerobic (involves the chemical reaction of food molecules with molecular oxygen) or anaerobic (without additional oxygen).

Answer number 2
Explanation:
So in Geology, Precipitation of rock layers took place over the last hundreds of millions of years...During that process many living organisms have died and are precipitated with the rock layers... Let me explain with an example.
Dinasours went extinct Million years ago while the Dodo bird went extinct a couple of hundred years ago
Would you expect to find Dinasour fossils in newer rock layers or the dodo? lets's say 200m deep? Dodo for sure, Dinasour fossils are waay too old to be found at such shallow deeps that's why fossils in newer layer of rocks are absolutely younger than fossils found at deeper layers
