Atmosphere provides chemicals needed for life.
Answer (1)
The atmosphere provides essential chemicals for life, primarily through its oxygen and carbon dioxide content. Oxygen is crucial for respiration in most living organisms, while carbon dioxide is vital for photosynthesis in plants. The atmosphere also contains nitrogen, which is essential for plant growth when converted into usable forms by bacteria. Additionally, the atmosphere plays a crucial role in regulating temperature and protecting Earth from harmful radiation. Here's a more detailed breakdown:Oxygen:The atmosphere contains roughly 21% oxygen, a vital component for respiration in animals and many plants. Carbon Dioxide:Plants use carbon dioxide, along with water and sunlight, to produce their food through photosynthesis, releasing oxygen as a byproduct. Nitrogen:While not directly used by most organisms, nitrogen in the atmosphere is converted into usable forms by soil bacteria, which are then absorbed by plants. Temperature Regulation:The atmosphere acts like a blanket, trapping heat and preventing extreme temperature fluctuations that would make the planet uninhabitable. Radiation Protection:The atmosphere filters out harmful ultraviolet radiation from the sun, protecting living organisms from damage.
