Carbon dioxide is available when autotrophs & heterotrophs release it into the air during ______________ ______________.
Carbon is released from _______________ ___________ when they are burned, which adds ___________ _________ to the atmosphere.

Answer 1

All living things are made of molecules that contain carbon (or carbon atoms bonded to other elements.)

During photosynthesis, green plants and algae convert carbon dioxide & water into glucose while releasing oxygen into the atmosphere.

Carbon dioxide is available when autotrophs & heterotrophs release it into the air during cellular respiration.

Carbon is released from fossil fuels when they are burned, which adds carbon dioxide to the atmosphere.
