Answer them all plz in order

1:Carbon dioxied

2:fossil fuels

3:Plants absorb carbon dioxide,water and sunlight to make their own food,grow and release oxygen through photosynthesis.\

4:Photosynthesis, Decomposition, Respiration and Combustion

5 :Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
