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

Carbon Dioxide

PHOTOSYNTHESIS

Plants make food and oxygen in the process of photosynthesis.

Plants release the oxygen into the air.

Food Oxygen

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.
