• It absorbs carbon dioxide from the atmosphere.

• It captures light energy from the sun.

• It releases oxygen as a byproduct.

• It provides water to the plant cells.

Which statement provides evidence that living systems follow the Law of Conservation of Mass?

• Plants grow by creating new matter from sunlight.

• The mass of a tree increases as it absorbs sunlight.

• The mass of what's needed in photosynthesis equals the mass of what's released.

• Animals gain mass by breathing in oxygen.

Explain how light intensity affects the rate of photosynthesis.

• Increased light intensity decreases the rate of photosynthesis.

• Increased light intensity increases the rate of photosynthesis up to a point.

• Light intensity has no effect on photosynthesis.

• Decreased light intensity increases the rate of photosynthesis.

How does the Law of Conservation of Energy apply to photosynthesis and cellular respiration?

• Energy is created during photosynthesis and destroyed during cellular respiration.

• Energy is neither created nor destroyed; it is transformed from one form to another.

• Energy is only conserved in photosynthesis, not in cellular respiration.

• Energy is lost as heat in both processes.
