Front

What happens to the carbon dioxide–oxygen cycle if Earth's large forests are cut down?

Back

There would be more carbon dioxide in the atmosphere because fewer plants would be using it to produce their own food.

Front

How do birds interact with nonliving parts of their environment?

Back

Birds react to morning sunlight by singing, drink and take baths in puddles of water, and respond to cold temperatures by fluffing their feathers.

Light travels in straight lines and reflects from the surface of the mirror.

Front

What is an example of a living organism that depends on another living organism to survive?

Back

Bacteria living in the mouth of a horse.

Front

What is the role of plants in the carbon dioxide–oxygen cycle?

Back

Plants use carbon dioxide to produce oxygen through photosynthesis.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to create their own food and release oxygen.

Front

What is the importance of sunlight for plants?

Back

Sunlight is essential for photosynthesis, allowing plants to produce food.

Front

How do animals contribute to the carbon dioxide–oxygen cycle?

Back

Animals breathe in oxygen and exhale carbon dioxide, which plants use.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their environment.
