Understanding the Carbon Cycle and Productivity in Different Latitudes

These flashcards cover key concepts regarding the carbon cycle, including photosynthesis, respiration, the role of decomposers, and changes in carbon uptake across different latitudes.

What is the primary contribution of plants in the carbon cycle?

Photosynthesis where plants absorb CO₂ and convert it into glucose.

How does respiration impact the carbon cycle?

Plants, animals, and microbes release CO₂ back into the atmosphere as they break down glucose for energy.

What is the trend in carbon uptake identified by scientists?

Carbon uptake is increasing in middle and high latitudes of the Northern Hemisphere, while less carbon is absorbed in the tropics and Southern Hemisphere.

What is the composition of a tree in terms of carbon?

Approximately 50% of a tree is made up of carbon.

What role do decomposers play in the carbon cycle?

Decomposers, like bacteria and fungi, break down organic material, returning carbon to the soil and atmosphere.
