How do students grow taller?

• Students grow taller when they use food molecules they eat to build large molecules that make new cells

• Students grow taller when they use the food molecules they eat to make up new cells without changing the food molecules

Why do plants usually grow in soil?

• Plants use their roots to take in food from the soil

• Plants use their roots to take in non-food nutrients and water from the soil.

• Plants use their roots to take in oxygen

• Plants use their roots to take in carbon dioxide from the soil.

Carbon dioxide and oxygen are important resources in ecosystems and are

• stored in animals in the ecosystem

• lost due to the activities of decomposers

• released by the process of photosynthesis

• recycled through the activity of living and nonliving systems

organisms contain compounds such as protein, starches, and fats. The chemical bonds in these compounds can be a source of

• amino acids

• energy

• simple sugars

• enzymes

What would be the result of removing carbon dioxide from the environment on plants?

• nothing would change

• Increase sugar production

• Increase oxygen production

• Decrease sugar production until it eventually stops

What is the name of the process in plants that creates food for plants?

• Cellular respiration

• photosynthesis

• glycolosis

• Fermentation
