A series of physical and chemical changes occur during the process of digestion.

Which of the following processes best describes a physical change that occurs during digestion?

• Stomach acid breaks down proteins

• Bile breaks down fat

• Saliva breaking down large molecules into smaller molecules

• Chewing food to break down large pieces so they can be swallowed

Animals are consumers, meaning they need to eat food for energy because they cannot make their own.

Which energy transformation is taking place when an animal eats food so it can

keep warm?

• mechanical to thermal

• mechanical to radiant

• chemical to thermal

• radiant to chemical

What stimulus is the seedling responding to that causes the roots and stem to grow in

opposite directions?

• Water

• Light

• Gravity

• Temperature

What must happen for a seed to emerge from the soil as a seedling?

• The soil must erode and expose the seed to the sunlight.

• An animal searching for food must disrupt the soil.

• The seed must exert a force to push a shoot up through the soil.

• Another plant must die to make room for the new plant.
