Matter & Energy in Ecosystems Amplify Unit Review

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 in an ecosystem?

Back

Only plants and some algae 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

Which organisms carry out cellular respiration in an ecosystem?

Back

All organisms, including plants, animals, and decomposers, carry out cellular respiration.

Front

What role do decomposers play 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 energy storage molecules in plants during photosynthesis?

Back

Plants take in carbon from the air and use it to create energy storage molecules, such as glucose.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, carbon dioxide, and water.

Front

Why is sunlight important for plants?

Back

Sunlight provides the energy needed for photosynthesis, allowing plants to produce food and energy.

Front

What is the role of the sun in ecosystems?

Back

The sun is the primary source of energy for ecosystems, driving processes like photosynthesis and influencing climate.
