This gas is taken in by plants during photosynthesis and is used to make glucose.

What is carbon dioxide?

100

What is the main purpose of cellular respiration in living organisms?

What is to produce energy from food. 

100

When dead plants and animals decompose, they release carbon back into the soil and atmosphere through this process.

What is decomposition?

100

In a chemical reaction, the total mass of the input is equal to the total mass of the output. This illustrates this law.

What is the Law of Conservation of Mass?

100

This type of scientific statement explains a basic principle that always occurs under certain conditions, such as gravity.

What is a law?

200

This process happens in a plant’s leaves and uses sunlight, water, and carbon dioxide to create food.

What is photosynthesis?

200

In what cell structure does most of cellular respiration take place?

What is the mitochondria. 

200

This term describes carbon that has been stored underground for millions of years in the form of coal, oil, or natural gas.

What are fossil fuels?

200

When a piece of wood burns, the mass of the wood is not lost but is transformed into these substances.

What are gases (such as carbon dioxide) and ash?

200

This type of scientific explanation is based on evidence and tested repeatedly, but it may change or evolve as new evidence is discovered.

What is a theory?

300

Name the part of the plant cell where photosynthesis occurs.

What is the chloroplast?

300

What gas do organisms take in for cellular respiration?

What is oxygen?

300

This process is used by factories that use fossil fuels and releases carbon dioxide into the atmosphere

What is combustion?
300

In a closed system, the total amount of energy before and after a reaction is the same. This is an example of this law.

What is the Law of Conservation of Energy?

300

This organelle functions as a storage compartment.

What is a vacuole?

400

The green pigment in plants that captures light energy from the Sun.

What is chlorophyll?

400

This is the name of the sugar molecule broken down during cellular respiration to release energy.

What is glucose?

400

This is the process by which plants take in carbon dioxide and produce oxygen.

What is photosynthesis?

400

In an experiment where a candle burns, the mass of the wax and oxygen in the air before and after the candle burns is the same, even though new substances are formed. This demonstrates the principle of this law.

What is the Law of Conservation of Mass?

400

This organelle contains genetic information.

What is a nucleus?

500

These are the two main products of photosynthesis.

What are glucose and oxygen?

500

What is/are the output(s) of cellular respiration?

What is water, carbon dioxide, and chemical energy?

500

This reservoir stores carbon in icebergs and glaciers.

What is the cryosphere?

500

When you heat water on a stove, the heat energy transfers to the water, but the total amount of energy remains constant. This is an example of this law in action.

What is the Law of Conservation of Energy?

500

Arrows in food webs represent this process.

What is energy flow?
