1. The scientific term for the process in which producers consume carbon dioxide and release oxygen is "Photosynthesis".
2. The scientific term for the process in which organisms liberate energy in the presence of oxygen is "Cellular Respiration".

Choose the correct answer:

1. True. Photosynthesis, cellular respiration, and combustion are indeed the main processes in carbon-oxygen cycles.
2. True. Carbon is an essential element in bones and proteins.
3. False. Producers use carbon dioxide during photosynthesis, not cellular respiration.
4. False. There is a direct relation between the carbon cycle and the oxygen cycle.

What happens if:

1. Burning trees increases the amount of carbon dioxide in the atmosphere because combustion (burning) is a chemical reaction that releases carbon dioxide. This can contribute to global warming. The amount of oxygen will decrease because trees produce oxygen through photosynthesis.
2. An elevation of carbon dioxide percentage in the air can lead to several environmental issues, including global warming and climate change. This is because carbon dioxide is a greenhouse gas that traps heat in the Earth's atmosphere. It can also lead to ocean acidification, as more carbon dioxide dissolves into the oceans.
