biomes.
A. The elevation determines whether
people can see and enjoy the plants.
B. Elevation determines whether the
plants get enough sunlight.
C. Elevation does not influence what
types of plants can grow in a certain
biome .
D. The elevation helps to determine
the temperature of the biome.
Going Over the Question of the Day
There are many factors that influence the number of
different kinds of plants in a biome. Why is elevation, or
height, a factor that influences what kinds of plants can live
in any certain biome on Earth?
The correct answer:
D. The elevation helps to determine the temperature of the biome.
Why does elevation determine temperature?
• The higher up you go in altitude, the colder it gets
• That’s why you see snow on the top of mountains!
• How will plants differ in different temperatures?
• You have cacti in hot dry temperatures!
• You have big leaved plants in hot wet temperatures!
• You have trees that drops their leaves in places with 4 seasons!
• You have evergreen trees in places with colder temperatures!

6th Grade Science TCAP:
Reviewing Relationship in Ecology!
(from Unit 2: Ecology)
Today’s Agenda:

Part I: Reviewing Relevant Ecology Terms
Part II: Reviewing Biomes
• Ecology Practice Quiz (15 minutes)
Part I: Reviewing Relevant
Ecology Terms
• We’re going to do a quick review of some
terms.
• Then we’ll practice our terms with some
questions
• All of these terms should be on your vocab
ring!
• Quickly write them down and their definitions
when you see “Write these definitions down”
• Ms. McGuirk tried to make the definitions as
short as possible!
Abiotic versus Biotic
• Abiotic: nonliving
• Biotic: living
Write these
definitions
down!
Analyzing Abiotic/Biotic Relationships
Which abiotic factor is the basis for this ecosystem?
Water!
Producers versus Consumer versus
Decomposer
• Producer: an organism that uses the sun light
to make its own food (a.k.a. autotroph).
• Consumer: an organism that depends on other
organisms for food (a.k.a. heterotroph).
• Decomposer: an organism that breaks down
other organisms to get energy and returns
nutrients to the soil.
Write these
definitions
down!
Analyzing
Producer/Consumer/Decomposer
Relationships
When looking
for a
producer,
look for the
organisms
with no
arrows
pointing to it.
Which is a producer in the Arctic Food Web above?
Phytoplankton!

Which organism in this food web can be a primary
and secondary consumer?
Mouse!
Food Chain versus Food Web
versus Energy Pyramid
• Food
Chain: shows only one line of
\
feeding relationships.
• Food Web: shows many feeding
relationships within an ecosystem.
• Energy Pyramid: shows how energy
decreases as you travel from producer 
tertiary consumer.
Write these
definitions
down!
Analyzing Feeding Relationship
Diagrams
How would you describe
the way that energy is
transferred in this
pyramid?
The amount of energy decreases up from the
plankton level.
Part II: Reviewing Biomes
• The last half of our review will be a team
discussion.
• Your coach will leave the picture slide on the
board for 15 seconds for you to look at.
• Then, you will raise your hand to participate in a
discussion about the biomes we learned about!
Temperate Deciduous Forest Biome
Temperate Deciduous Forest Biome
• What is so unique about this biome?
This biome has trees that drop their leaves.
These trees are called deciduous. Memphis is
located in this biome!
• What kinds of plants will you find?
You will find deciduous trees and plants like
grass and ferns.
• What kinds of animals will you find?
Squirrels, foxes, deer and birds.
Coniferous Forest Biome (Taiga)
Coniferous Forest Biome (Taiga)
• What is so unique about this biome?
This biome has trees whose leaves remain
evergreen – remember, Coniferous sounds like
Christmas, and these are the kinds of trees we see
at that time of the year!
• What kinds of plants will you find?
Evergreen trees (conifers), which have pointy
needles for leaves and pinecones.
• What kinds of animals will you find?
Similar to animals in a deciduous forest biome,
but elk/moose instead of deer.
Tropical Rainforest Biome
Tropical Rainforest Biome
• What is so unique about this biome?
Its climate! It is very warm and very wet all year
long!
• What kinds of plants will you find?
Big-leaved trees and plants.
• What kinds of animals will you find?
Brightly colored birds, frogs, snakes, tigers,
monkeys, and millions of insects!
Grassland Biome
Prairie (North America)
Savanna (Africa)
Grassland Biome
• What is so unique about this biome?
This biome has FEW trees – that’s why it is
called a GRASSland. Because of this, there are
many large herbivores that live here (i.e. Buffalo
and Zebra)
• What kinds of plants will you find?
GRASS (duh!) – and very few trees.
• What kinds of animals will you find?
Buffalo, Horses, Zebra, Giraffe, Rhino, Lions,
Elephants
Desert Biome
Desert Biome
• What is so unique about this biome?
Its climate – it is very hot and dry. Because of
this, it lacks many plants and trees.
• What kinds of plants will you find?
Cactus and other succulent plants that can store
water.
• What kinds of animals will you find?
Many cold-blooded animals that hide during the
day and come out at night. Lizards, scorpions,
snakes, and small rodents.
Tundra Biome
Tundra Biome
• What is so unique about this biome?
It is so cold in this biome that a layer of soil is
permanently frozen – this is called permafrost.
• What kinds of plants will you find?
Small shrubs and lichens (a moss-like producer)
– it is too cold and the soil is frozen so other
plants and trees cannot put their roots far enough
in the ground to grow.
• What kinds of animals will you find?
Animals with a lot of white fur – polar bears, musk
oxen, foxes, wolves, and rabbits.
Ecology Practice Quiz
(15 minutes)
• Log into Quia and click on March Madness
Week 2 Ecology Practice Quiz
• The secret word is “biome”
• You will have the last portion of class to answer
10 practice questions on this topic.
• Once you submit your answers, make sure you
review the questions you got wrong!
• If you finish early with the quiz, you can view
the link on my Quia for “March Madness: Week
2”
• Play “Producers Consumers Decomposers”
