C ARBON D IOXIDE - O XYGEN
C YCLE

Plants and animals are linked for
survival through the carbon dioxideoxygen cycle.
P HOTOSYNTHESIS

To undergo photosynthesis, plants need:

sunlight

water

carbon dioxide
P HOTOSYNTHESIS

Plants make food and oxygen in
the process of photosynthesis.

Plants release the oxygen into the
air.
C ARBON DIOXIDE

Carbon dioxide is found in the air.

It gets there from:

volcanoes erupting

burning fossil fuels

animals
A NIMALS

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.
C ARBON
DIOXIDE - OXYGEN
CYCLE
Carbon dioxide released
during respiration
Plants use the carbon dioxide
produced by animals to perform
the process of photosynthesis.
During photosynthesis, oxygen is
produced.
Oxygen released
during photosynthesis
Animals, in turn, use the
oxygen in the process of
respiration to release
energy from the food they
eat. As a product of
respiration, animals make
carbon dioxide.
