Photosynthesis:The process used by plants, algae, and some bacteria to convert sunlight into chemical energy (glucose) using carbon dioxide and releasing oxygen as a byproduct.
Aerobic Respiration:A metabolic process where cells use oxygen to produce energy from food, releasing carbon dioxide as waste.
Ozone Layer: A layer in Earth's stratosphere containing high concentrations of ozone (O3). It absorbs most of the Sun's harmful ultraviolet radiation.
