Carbon in Soil

Carbon is also found in soil
humus (because it is made up of
dead organisms).

Carbon in Fossil Fuels

When we burn fossil fuels (they once were living organisms), carbon
dioxide is released into the air.

Fill in the Blank

When we burn _______ fuels, CO2 is released back into the air?

Carbon in Organisms

When organisms die, they are broke down (decomposed) by fungi, bacteria, and
other decomposers. During this decay process, carbon dioxide is released into the
air.

Plants and Carbon

●

Plants use Carbon
Dioxide to perform
photosynthesis

●

Plants give off Oxygen.
(waste gas)

Multiple Choice

What process do plants use carbon dioxide for?

• cellular respiration

• carbon cycle

• photosynthesis

• nitrogen cycle

Animals and Carbon

●Animals use Oxygen to live.

●Animals give off Carbon
Dioxide. (waste gas)

Match

Match the following

• Animals use this to live

• Animals give this off

• What cycle are we studying today?

oxygen

carbon dioxide

carbon cycle

• oxygen

• carbon dioxide

• carbon cycle

Too Much Carbon?

We are cutting down too many
trees and plowing up fields.

We are also burning too many
fossil fuels.

The amount of Carbon Dioxide
in the atmosphere is increasing.

This is causing our planet to
warm up.

This process is called Global
Warming and The Greenhouse
Effect.
