Front

What are the characteristics of a tropical rainforest biome?

Back

Tropical rainforests are characterized by high rainfall, warm temperatures, and a diverse range of plant and animal species.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is crucial for regulating Earth's climate and supporting life by cycling carbon through the atmosphere, oceans, and living organisms.
