Question

Поясни чому без повітряна нашій планеті не існувало б життя

Answer 1

Ответ:

Для всіх живих організмів, є спільна риса -- це дихання. А для дихання потрібний газ кисень, який по своїй фізіології є безбарвним і без запаху. Лише кисень придатний для дихання.

Тому, без повітря, життя існувати не може!

Answer 2

Ответ:

Повітря-це частина природи. Без повітря на землі не було б життя ,адже в ньому міститься кисень,яким дихають живі істоти.Якщо повітря забруднене,то всім організмам важко дихати,вони хворіють і навіть гинуть.Людям ,рослинам і тваринам для дихання потрібне чисте повітря.

Answer 3

Why Life Couldn't Exist Without Air on Our Planet

Life as we know it couldn't exist without air on our planet for several reasons:

Composition of the Atmosphere: The Earth's atmosphere is primarily composed of nitrogen (78.08%), oxygen (20.96%), and trace amounts of other gases such as argon, carbon dioxide, and water vapor.

Essential for Respiration: Oxygen is essential for the process of respiration in most living organisms. It is used to break down glucose and other organic molecules to produce energy in the form of adenosine triphosphate (ATP) through cellular respiration.

Carbon Dioxide and Photosynthesis: Plants and other autotrophic organisms use carbon dioxide during photosynthesis to produce glucose and oxygen. This process is vital for the production of food and the release of oxygen into the atmosphere.

Regulation of Temperature: The atmosphere helps regulate the Earth's temperature by trapping heat from the sun, preventing extreme temperature fluctuations that would make life unsustainable.

Protection from Solar Radiation: The atmosphere provides a shield against harmful solar radiation, including ultraviolet (UV) rays, which can be damaging to living organisms.

In summary, the composition of the Earth's atmosphere, particularly the presence of oxygen and carbon dioxide, is essential for the processes of respiration and photosynthesis, which are fundamental to the existence of life as we know it.

It's clear that without the specific composition and properties of our planet's atmosphere, life as we understand it would not be sustainable.
