Matter and Energy in Ecosystems

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

What is the primary gas taken in by plants during photosynthesis?

Back

Carbon dioxide is the primary gas taken in by plants during photosynthesis.

Front

What is the primary gas released by plants during photosynthesis?

Back

Oxygen is the primary gas released by plants during photosynthesis.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed for plants to convert carbon dioxide and water into glucose and oxygen.

Front

What are energy storage molecules?

Back

Energy storage molecules are compounds that store energy for later use, such as glucose in plants.

Front

What elements make up glucose?

Back

Glucose is made up of carbon (C), hydrogen (H), and oxygen (O).

Front

Which organisms perform photosynthesis?

Back

Plants, algae, and some bacteria perform photosynthesis.

Front

What is the significance of photosynthesis in ecosystems?

Back

Photosynthesis is crucial for ecosystems as it produces oxygen and organic compounds that serve as food for other organisms.

Front

What is the process of cellular respiration?

Back

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

Front

How do decomposers fit into the ecosystem?

Back

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