Carbon, Oxygen, Water Cycle

Front

What process removes carbon dioxide from the atmosphere?

Back

Photosynthesis is the process by which plants convert carbon dioxide into oxygen and glucose using sunlight.

Front

What gas do humans release into the atmosphere when they breathe?

Back

Humans release carbon dioxide (CO2) into the atmosphere when they breathe out.

Front

What is the primary gas released when fossil fuels are burned?

Back

Carbon dioxide (CO2) is the primary gas released when fossil fuels are burned.

Front

What natural process can increase the amount of oxygen in the air?

Back

Planting more trees can increase the amount of oxygen in the air.

Front

Which substance do plants need to survive that is released by animals?

Back

Plants need carbon dioxide (CO2) to survive, which is released by animals during respiration.

Front

What is the role of the water cycle in the environment?

Back

The water cycle is essential for distributing water across the planet, supporting all forms of life.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the impact of deforestation on carbon dioxide levels?

Back

Deforestation increases carbon dioxide levels in the atmosphere because fewer trees are available to absorb CO2.

Front

How does combustion contribute to the carbon cycle?

Back

Combustion of fossil fuels releases carbon dioxide into the atmosphere, contributing to the carbon cycle.

Front

What is the significance of trees in the carbon cycle?

Back

Trees absorb carbon dioxide during photosynthesis, helping to regulate atmospheric CO2 levels.
