Front

What is the Law of Conservation of Mass?

Back

It states that mass cannot be created or destroyed; it only changes form.

Front

What is the Law of Conservation of Energy?

Back

It states that energy cannot be created or destroyed; it only changes form.

Front

How does photosynthesis demonstrate the Law of Conservation of Mass?

Back

The mass of carbon dioxide and water used equals the mass of glucose and oxygen produced.

Front

How does cellular respiration demonstrate the Law of Conservation of Energy?

Back

Energy stored in glucose is transformed into ATP, with no energy lost.

Front

What happens to matter during a chemical reaction in living systems?

Back

Matter is rearranged into new substances, but the total mass remains the same.

Front

How is energy transferred in living systems?

Back

Energy is transformed from one form to another, such as light energy to chemical energy in photosynthesis.

Front

How does the carbon cycle illustrate the Laws of Conservation of Mass and Energy?

Back

Carbon is recycled through organisms and the environment, and energy flows through the cycle without being lost.

Front

What evidence supports the Law of Conservation of Mass in ecosystems?

Back

The total mass of nutrients and waste in an ecosystem remains constant over time.

Front

What evidence supports the Law of Conservation of Energy in ecosystems?

Back

Energy flows through food chains, transforming from one form to another, but the total energy remains constant.

Front

Why is understanding these laws important for studying living systems?

Back

It helps explain how matter and energy are recycled and conserved in biological processes.
