Matter and Energy in Organisms

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

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

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

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?

• Living things change energy into matter.

• Some of the energy is used for life processes.

• Some energy disappears when living things are eaten.

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

What does this diagram show?

• It shows how matter can pass through an ecosystem.

• It shows each step in the correct order that carbon must pass through.

• It shows how more carbon is constantly being formed and passed along.

• It shows how carbon is running out because it is all being used up by animals.

• Nutrients are warm.

• Nutrients have mass.

• Nutrients can do work.

• Nutrients contain energy.

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 all of their energy by eating other organisms.

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

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

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

Decomposition is a physical and chemical process by which dead organic matter is broken down. Why is decomposition important to life processes?

• It helps return carbon and nutrients to the environment.

• Decomposition is important because everything breaks down.

Describe how plants and animals get the matter they need to survive.

• They go to Walmart and buy what they need

• Plants get the matter they need from their environment from their roots. Animals get the matter they need from eating food and by taking in water.
