1. Living things need water
75% of the Earth's surface is water
90% of a head of lettuce is water
67% of your body is water
Water is essential for all life on Earth
Humans can live for approximately 3 days without water

2. Living things need food
We get nutrients from food
Nutrients are carbohydrates, fats, proteins, vitamins and minerals
Nutrients allow you to grow, move and repair and maintain the cells in your body

3. Living things need energy
You need energy to walk, run, breathe, eat, digest, grow blink your eyes, beat your heart ....
You need energy when you sleep!
Energy comes from processing the foods we eat and breaking them down into nutrients

4. Living things need oxygen
Oxygen is used to breakdown the food we eat into nutrients.
Oxygen is needed in the muscles of your body
All living things need oxygen - though plants and fungus (mushrooms) don't need as much as animals

5. Living things need suitable living conditions
Life exists all over the planet from the depths of the ocean to the top of the tallest trees.
Organisms are adapted to living in all climates including those most harsh - bacteria can live in water 400C. Others can live in -90C conditions.
Most living things build shelters to protect them from the harsh conditions
