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, carbon dioxide, and water.

Front

Why are decomposers important in an ecosystem?

Back

Decomposers break down dead matter, recycling nutrients back into the ecosystem.

Front

What role do plants play in an ecosystem?

Back

Plants are producers that capture energy from sunlight and convert it into chemical energy through photosynthesis.

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

How does sunlight affect energy storage in plants?

Back

In sunlight, the number of energy storage molecules in plants increases as they perform photosynthesis.

Front

What happens to photosynthesis if carbon dioxide levels decrease?

Back

If carbon dioxide levels decrease, the rate of photosynthesis decreases.

Front

What is the role of carbon in living organisms?

Back

Carbon is a key element in organic molecules, essential for life, and is involved in processes like photosynthesis and cellular respiration.

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 obtain energy by eating other organisms, including plants and animals.

Front

What is the difference between herbivores, carnivores, and omnivores?

Back

Herbivores eat plants, carnivores eat animals, and omnivores eat both plants and animals.
