Why is the ability to move important to animals?

• • It helps them find food.

• • It helps them stay warm.

• • It helps them obtain oxygen.

• • It helps them differentiate cells.

What form of energy is stored in food?

• • heat

• • light energy

• • energy of motion

• • energy in molecules

How do organisms get the energy they need?

• • Plants get energy from fertilizers. Animals get energy from water.

• • Plants use energy from sunlight to make sugar molecules. Animals get energy from eating other organisms.

• • Plants do not need energy because they do not move. Animals get energy from food.

• • Plants get energy from the soil. Animals get energy directly from sunlight.

Dylan drew a diagram showing that certain organisms eat other organisms. The diagram included a caption stating that the amount of available energy decreases with each organism that is eaten. How is this explained by the law of conservation of energy?

• • Some energy disappears when living things are eaten.

• • Only small amounts of energy can be destroyed at a time.

• • Living things change energy into matter.

• • Some of the energy is used for life processes.

Some consumers, such as many flying insects, need large amounts of energy to grow and move from one place to another. How do consumers get energy to function?

• Consumers obtain some energy from other organisms and some from sunlight.

• Consumers convert light energy from the sun into chemical energy stored in food.

• • Consumers obtain most of their energy by absorbing it from their environments.

• • Consumers obtain all of their energy by eating other organisms.

What is the primary source of energy for all life on Earth?

• • The Sun

• • The Moon

• • The Ocean

• • The Wind

Why do animals need to consume other organisms for energy?

• • Because they can't produce their own energy

• • Because they need to maintain their body temperature

• • Because they need to breathe

• • Because they need to grow
