Processes that move carbon

The following slides will review the ways carbon can move through an ecosystem.

Producers remove carbon dioxide from the atmosphere for photosynthesis

​

​Some text here about the topic of discussion.

​Photosynthesis

all living things return Carbon dioxide to the atmosphere as they make energy from the food they eat.

​Cellular Respiration

As fossil fuels are burned, carbon dioxide is released into the atmosphere

​burning fossil fuels

Combustion

Decomposition /Decay

​Decaying organisms are broken down by decomposers and carbon dioxide is released into the soil
