Flashcards in Energy From The Sun Deck (53):
1

What happens as organisms are eaten?

Energy is used.

2

Why do we need energy?

We need energy for everything we do, like grow, play and sleep.

3

Where do we get our energy from?

We get our energy from the food we eat.

4

Why is the sun so important?

All energy and food chains start with the sun and it transferred from the sun.

5

How do plants make their own food?

They turn light energy from the sun into food.

6

Source of energy

The place we get the energy from.

7

What is energy?

Make things happen,move or change.

8

Nutrients

Substance in food that living things need to live,grow and stay healthy.

9

Why are plants called producers?

They make or produce their own food using light energy.

Sugar found in fruits, plants and honey

12

Carbon dioxide

A gas produced by humans and animals breathing

13

What types of energy does the sun provide us with?

Heat and light

14

What is an organism

Living things like plants or animals

15

Why do plants store their food?

16

What does a food chain show?

They show how living things get their food and how nutrients an energy are passed from one organism to another. They also show how living things depend on each other.

17

What could happen if a food chain is not balanced?
