Why do living things need air and water?

In order to survive, all living things need air, water, and food. Animals obtain their food from plants and other animals, which provides them with the energy they need to move and grow. An animal’s home (habitat) must provide these basic needs (air, water and food) along with shelter from bad weather and predators.

How do air and water make life possible on the Earth?

Earth’s amazing gaseous atmosphere is responsible for making life possible on this, the third planet from the Sun. Our atmosphere contains water vapor which helps to moderate our daily temperatures. Our atmosphere contains 21\% oxygen, which is necessary for us to breathe, 78\% nitrogen, and . 9\% argon.

What do living things need to survive on planet Earth?

In order to survive, animals need air, water, food, and shelter (protection from predators and the environment); plants need air, water, nutrients, and light.

What air needs to survive?

Animals need oxygen from air to carry out the reactions that release and transform energy from food. Carbon dioxide is released as a waste product during these processes. In mammals, including humans, air enters the body through the nose and mouth, and moves into the lungs.

Why is water so important to life on Earth?

It’s in all living things, whether they live at the bottom of the ocean or the driest desert. Water made life possible on Earth. Because of this, astrobiologists (scientists who search for life on other planets) think our best bet for finding life is to search for water. Almost all Earth’s water is in the oceans.

What is the importance of air to living things?

Air is important for living things. People need to breathe, and so do lots of other animals—and plants! Breathing is part of a process called respiration. During respiration, a living thing takes in oxygen from the air and gives out carbon dioxide.

What qualities are true of all life on Earth?

There aren’t many qualities that are true of all life on Earth, but the need for water is one of them. It’s in all living things, whether they live at the bottom of the ocean or the driest desert. Water made life possible on Earth.

Why are natural resources important to life on Earth?

All life on Earth depends on water, a vital natural resource. Natural resources—such as water, air, plants, wildlife, soil, and fossil fuels—are used by humans for the basic necessities of life, including food, drinking water, energy, and shelter.
