What air needs to survive?
The earth is surrounded by air, a mixture of extremely important gases such as oxygen, carbon dioxide, and nitrogen. These gases provide animals with oxygen for respiration to occur. It is vital that living things respire to get oxygen for living cells to function. Without air, there is no life.
Do animals need air?
In order to survive, animals need air, water, food, and shelter (protection from predators and the environment); plants need air, water, nutrients, and light. Every organism has its own way of making sure its basic needs are met.
Why do living things need air?
Living things need oxygen to survive because we can’t survive without oxygen. It is vital that living things respire to get the oxygen for living cells to function. Without air, there is no life. Plants use Carbon Dioxide (together with sunlight and water) to produce energy and give out Oxygen as a by-product.
How do we use air?
Important Uses of Air
- Sustain life and growth.
- Combustion.
- Maintaining Temperature.
- Supplier of Energy.
- Photosynthesis.
What happens when air Cannot enter the body?
Oxygen is the most important for keeping us alive because body cells need it for energy and growth. Without oxygen, the body’s cells would die. Carbon dioxide is the waste gas that is produced when carbon is combined with oxygen as part of the body’s energy-making processes.
Do all living things need oxygen to survive?
Most living things need oxygen to survive. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive. Although other animals may use different organs to breathe with, they all get oxygen into their bodies through respiration.
Why do plants and animals die without air?
Oxygen (O₂) is the main gas that is essential for life to exist. Without this gas, no organisms can survive. The organisms inhale oxygen (O₂) gas and exhale carbon dioxide (CO₂) gas.
How do humans get air?
Air flows in via our mouth or nose. The air then follows the windpipe, which splits first into two bronchi: one for each lung. The bronchi then split into smaller and smaller tubes that have tiny air sacs at their end called alveoli. We have millions of alveoli in our lungs!

What do living things need air to survive?
The earth is surrounded by air, a mixture of extremely important gases such as oxygen, carbon dioxide, and nitrogen. These gases provide animals with oxygen for respiration to occur. It also provides green plants with carbon dioxide for photosynthesis to happen.
What are some interesting things about the air?
