Plants and
photosynthesis
All organisms on Earth need energy to live and grow.
The primary source of all
energy that Earth’s organisms
need is the
Sun.
But animals can’t eat sunlight.
But animals can’t eat sunlight.
Animals get energy by consuming (eating) other organisms (plants or animals).
Animals are consumers.

Animals are consumers.
Animals must eat (consume) to get the energy they need.
But there is one type of organism that can produce food from sunlight energy.
PlantsPlants are producers.
Produce means “to make.”
Producers make food from sunlight energy.

Producers make food from
sunlight energy.
Plants are producers. They make food.Only plants can make food.
Plants make food in their
leaves.
A green material in leaves called
chlorophyll (klor oh fil)
turns light energy from the sun into chemical energy (sugar).
Plants must have three things in order to make food.

Plants get the CO2, carbon dioxide, they need from the air.
CO2 (carbon dioxide)is a gas that makes up about 1% of Earth’s atmosphere.
Plants get the water they need from their roots.

Plants “put food together” using light energy in the process called photosynthesis.
Plants take in carbon dioxide (CO2) and use it during photosynthesis.
Plants release (throw away)
oxygen as a waste product as they make
food.
Plants release (throw away)
oxygen as a waste product as they make
food. Oxygen is a gas that makes up 21% of the air.
Plants can’t live without CO2 and must release oxygen.
Animals can’t live without oxygen and must release CO2.
This is a very important
balance for life on Earth.
