Biomagnification

Front

What is the primary role of photosynthesis in the carbon cycle?

Back

To convert carbon dioxide into glucose using sunlight.

Front

What is the significance of cellular respiration in the biogeochemical cycles?

Back

It releases carbon dioxide back into the atmosphere as organisms break down glucose for energy.
