Carbon Dioxide Oxygen Cycle

What is happening at 1?

• respiration: releasing CO₂

• decomposing CO₂ in the soil

• photosynthesis: absorbing CO₂

• turning CO₂ from the atmosphere into organic molecules

How does the carbon in grass become part of a lion?

• The lion eats the grass

• Carbon from grass doesn't end up in a lion. 

• The carbon ends up in the lion's food chain. 

• The lion breathes in carbon given out by the plant
