How do plants obtain the water, carbon dioxide, and energy they use for this process?

• A. Carbon dioxide is absorbed from the soil, water is taken in by the stems, and energy comes from sugars stored in the plant.

• B. Carbon dioxide enters through the leaves, water enters through roots, and light energy is captured by the chlorophyll in plant cells.

• C. Water enters as rain falls on the stems, carbon dioxide is absorbed from fertilizer, and energy comes from sunlight heating soil around the plant’s roots.

• D. Carbon dioxide and chemical energy are absorbed through the roots and the leaves absorb water from the air.

How does blowing up a balloon provide evidence that air is matter?

• It shows that air has kinetic energy.

• It shows that air takes up space.

• It shows that air contains oxygen.

• It shows that air is a solid.

From which molecules do organisms get energy to perform daily activities?

• molecules of ATP

• molecules of water

• molecules of oxygen

Cellular respiration, or anaerobic respiration, occurs without oxygen. During anaerobic respiration, lactic acid is produced. When people do certain strenuous physical activities, the cells of their muscles may produce lactic acid. Which of these activities would most likely result in a buildup of lactic acid?

• bowling

• golf

• running

• walking

Organisms store energy for future use. Which of the following is an example of stored energy that occurs as part of the carbon cycle?

• A. Plants release carbon dioxide into the environment.

• B. Plants hold water in their leaves and stems.

• C. Animals radiate heat into the environment.

• D. Animals store glucose in cells.

Energy is transferred between certain organisms in an ecosystem. Which evidence supports the claim that the seagrass is a producer?

• It uses energy from the sun to make food.

• It creates energy needed by the ecosystem.

• It is eaten by other organisms.

• It releases nutrients into the soil.

The graph shows the changes in carbon dioxide in the atmosphere over several years. Each year, the amount of carbon dioxide decreased in the spring and summer and increased again in the fall and winter. Which statement best explains the yearly cycle shown in the data?

• The rate of cellular respiration increases during warmer months.

• The rate of photosynthesis decreases in the winter because many plants in cold climates die or lose their leaves.

• There is a time lapse between the processes of photosynthesis and respiration in the carbon cycle.

• The volume of carbon dioxide depends on the air temperature.

What happens to glucose inside a cell during cellular respiration?

• The cell uses ATP to break down glucose.

• The cell uses water to break down glucose.

• The cell uses oxygen to break down glucose.

• The cell uses nitrogen to break down glucose.
