Carbon Dioxide­ Oxygen Cycle
∞

Plants and animals are linked for
survival through the carbon
dioxide-oxygen cycle.
Photosynthesis

To undergo photosynthesis, plants
need:

sunlight

water

carbon dioxide
Carbo
n
Dioxid
Photosynthesis

Plants make food and oxygen in
the process of photosynthesis.
Food

Oxygen
Plants release the oxygen into the
air.
Carbon dioxide

Carbon dioxide is found in the
air.

It gets there from:

volcanoes erupting

burning fossil fuels

animals
Animals

Plants make food through a process
called photosynthesis

When animals consume the plants,
they are consuming energy from the
plants.

Animals convert the plant’s energy into
the energy they need to grow and
thrive.
