Answer 1

Answer:

Oxygen cycle

Respiration: All living organisms take in simple sugars (glucose) and oxygen and release carbon dioxide, water and energy. b. Combustion: During the processes of combustion (or burning), oxygen reacts with carbon to form carbon dioxide gas

Answer 2

Answer:

The oxygen cycle is the biogeochemical transitions of oxygen atoms between different oxidation states in ions, oxides, and molecules through redox reactions within and between the spheres/reservoirs of the planet Earth

When new life is formed, carbon forms key molecules like protein and DNA. It's also found in our atmosphere in the form of carbon dioxide or CO2. The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again.
