Photosynthesis

Question 12

Carbon Cycle steps where Carbon moves from plants to animals.

Answer 12

Consumption or food chains

Question 13

Through ______, the carbon that is in plants, moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

Answer 13

food chains

Question 14

Carbon Cycle Steps where the Carbon moves from plants and animals to soil. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. The same is buried and will and will become fossil fuels in millions and millions of years

Answer 14

Decomposition

Question 15

Carbon Cycles Steps where carbon moves from the living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO²) into the atmosphere.
