Back

Carbon from grass becomes part of a lion's body through the food chain, as the lion consumes the grass or animals that have eaten the grass.

Front

What is the role of photosynthesis in the carbon cycle?

Back

Photosynthesis allows plants to absorb carbon dioxide from the atmosphere and convert it into organic matter.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which organisms convert glucose and oxygen into energy, releasing carbon dioxide as a byproduct.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is significant because it regulates the levels of carbon dioxide in the atmosphere, which is essential for maintaining life on Earth.

Front

What are fossil fuels, and how do they relate to the carbon cycle?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms, and their combustion releases stored carbon back into the atmosphere.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases, including carbon dioxide.
