Carbon Sink/Reservoirs

Placed where carbon is stored for a long time

Examples of sinks/reservoirs

Sugar

Carbon dioxide in the atmosphere or dissolved in water

Rocks, soil, and fossil fuels

Organisms

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
