Matter & Energy in Ecosystems Amplify Unit Test

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

Which organisms carry out photosynthesis?

Back

Only plants, algae, and some bacteria carry out photosynthesis.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which organisms convert glucose and oxygen into energy, carbon dioxide, and water.

Front

Do all organisms perform cellular respiration?

Back

Yes, all organisms, including plants, animals, and decomposers, perform cellular respiration.

Front

What happens to energy storage molecules during photosynthesis?

Back

The number of energy storage molecules, such as glucose, increases during photosynthesis.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and helping to recycle matter in the ecosystem.

Front

How does carbon move in an ecosystem?

Back

Carbon moves into the air through processes like respiration and combustion, and it moves out of the air through photosynthesis.

Front

What happens to carbon in the air when plants photosynthesize?

Back

During photosynthesis, plants absorb carbon dioxide from the air, reducing the amount of carbon in the atmosphere.

Front

What is the relationship between energy storage molecules and carbon in plants?

Back

As the number of energy storage molecules in plants increases, the amount of carbon in the plants also increases.

Front

What is the significance of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for photosynthesis to occur, allowing plants to convert carbon dioxide and water into glucose.
