Macronutrient
Carbon
Oxygen
Hydrogen
Nitrogen
Phosphorus
Where do plants
get this from?
Why do plants need
it?
 From the air in
the form of CO2
 To produce food
through
photosynthesis
 To build many
different organic
compounds
 From many
carbohydrate-rich
foods such as
bread, rice, and
potatoes
 To build many
different organic
compounds
Carbon gets its name from
the latin word carbo which
means coal
 Like all living things,
plants need oxygen
to survive
 From the air in the
form of O2
 Like all living
things, humans
need oxygen to
survive
Oxygen is blue when it’s a
liquid.
 Major component of
many compounds
made by plants
 From all types of
food
 Major component
of many
compounds made
by humans
About 10 percent of the
weight of living organisms
is hydrogen, mainly in H20,
proteins, and fat.
 Used to build
proteins and DNA
 Protein-rich foods,
such as meat, nuts,
soy, milk etc.
 Used to build
proteins and DNA
It is used in explosives.
 Used to build DNA
Discovered in 1669, by
extracting it from buckets
of urine.
Referred to as the “Devil’s
Element” because it was
the thirteenth element and
its explosive properties.
 By using energy
from light to
break H2O
molecules
 From the air in
the form of O2
 By using energy
from light to
break H2O
molecules
 Nitrogen-fixing
bacteria in their
roots convert N2
into NO3 Dead and
decaying matter
in the soil
 In the soil from
rocks
 Used to build DNA
Where do humans
get this from?
 Protein-rich foods,
such as meat, nuts,
soy, milk etc.
Why do humans
need it?
Fun Fact
IMPORTANT: The Provincial Achievement Test requires that you know the five macronutrients that are highlighted in green! You don’t need
to know the fun facts of the macronutrients.
Potassium
 Dead and
decaying matter
in the soil
 Regulates opening
and closing of
stomata
 Many different
types of food such
as avocado,
spinach, banana,
coconut water, etc.
Magnesium
 Dead and
decaying matter
in the soil
 Used to build
chlorophyll
 From dark green,
leafy vegetables
Calcium
 Dead and
decaying matter
in the soil
 Used to build the
cell walls
 Dairy products,
kale, broccoli, fish
bones, and grains
Sulfur
 Dead and
decaying matter
in the soil
 Used to build
proteins
 Protein-rich foods,
especially eggs
 Smelly vegetables
such as onions,
garlic, cabbage, etc.
 Maintains blood
pressure, and help
transmit nerve
signals
 For many things,
such as to protect
blood vessels,
nerve and muscle
function, maintains
a healthy immune
system, etc.
 For strong bones
and teeth, and to
allow muscles to
move
 Used to build
proteins
It’s the seventh most
abundant element on
earth.
Magnesium is not found on
earth as a free element.
Calcium is a mineral that
plays a key role in causing
hearts to contract.
Has been used since
ancient times and is
mentioned in the Bible and
the Torah
