Chapter 2 Review: Matter and Energy in Ecosystems

Front

What is cellular respiration?

Back

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

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What are producers in an ecosystem?

Back

Producers are organisms, like plants, that create their own food through photosynthesis.

Front

What are consumers in an ecosystem?

Back

Consumers are organisms that cannot produce their own food and must eat other organisms for energy.

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

What are the products of cellular respiration?

Back

The products of cellular respiration are energy, water, and carbon dioxide.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

How do plants obtain energy?

Back

Plants obtain energy through photosynthesis, using sunlight to convert carbon dioxide and water into glucose.

Front

What is the significance of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a key reactant in photosynthesis, as it is used by plants to produce glucose.

Front

What is the significance of oxygen in cellular respiration?

Back

Oxygen is a key reactant in cellular respiration, as it is used to help convert glucose into energy.
