Chapter 6: Biomes
Biomes
Has anyone ever heard of biomes before?– Do you recognize any part of the word?
Biomes are related to ecosystems, which was our last unit
Biomes Biomes – A large region characterized
by a specific type of climate and certain types of plants and animal communities (ecosystems)– Each biome is made up of many
ecosystems
There is a lot in that definition, but look at it and see what you already recognize
Biomes
Each biome has it’s own climate and certain types of plants and animals
You can tell a lot about the Biome just from the name
So we’re going to play a little game
Biomes Game
I’m going to put up a list of several of the different biomes
You will then have to put them in order based on different categories that I give you– Remember this is all based on what you
already know about these places and words
Biomes Game Different Types:
Polar Ice Tropical Rain
Forest Temperate
Grassland Desert Tropical Savanna Tundra
Categories:
1. Alphabetical2. Hottest to
Coldest3. Most
precipitation to least rain
4. Closest to Philly to farthest from Philly
Biomes
There are 10 different types of terrestrial biomes, and we will learn about most of them:
1. Polar Ice 6. Tropical Rain Forest2. Temperate Forest 7. Tropical Savanna3. Taiga 8. Temperate Grassland4. Chaparral 9. Desert5. Tundra 10. Mountains
Biomes Map
Biome Activity
You’re going to make your own BIOME map
Follow the instructions on your paper
Biomes Biomes are often defined by their
vegetation
The plants that grow in an area determine the other organisms that can live there– Why is this true?– Plants are the producers, the base of the
food chain, so all consumers depend on them
Climate
But what determines what plants can grow where?– The weather!
Climate – the weather conditions in an area over a long period of time– Includes temperature, precipitation,
winds, humidity, etc.
Climate of a Biome The climate of a biome is based on
two things:1. Average Temperature2. Average Precipitation
Remember that precipitation is not just rain
Only certain organisms can live in certain areas
– You wouldn’t find a polar bear in a tropical rain forest (why?)
Climate Precipitation is also a limiting factor
in a biome Every organism needs water, but
some need more than others– We need more water than an ant, but
less water than a big Oak Tree So where there is a lot of rain, there
can be a lot of big trees and plant growth– This means more organisms in general
Latitude and Altitude
What are some factors that can affect weather?– How close to the equator you are
The closer the hotter– How high up you are
The higher the colder Latitude – distance north or south of
the equator Altitude – height above sea level
Latitude and Altitude Activity
Picture the room as the globe
The front is the North Pole The back where the windows are is
the South Pole The middle is the equator
Latitude and Altitude Who in the room would be the
hottest and why?
Who would be the coldest?
What types of biomes, plants and animals would be living in your part of the world?
Latitude and Altitude
Now, how can we change altitude? – Everyone is sitting on the same type of
chair
We’re going to have to stand on tables and sit on the floor
How would that change the climate?
Latitude and Altitude
Climatograms or Climatographs Climatograms – a
graph that shows both the average temp and precipitation for a given biome
The line shows the Temperature
The bars show the precipitation
Temp
Precip.
Climatograms
Which month had the most rain?
Which month had the least rain?
Which month has the highest temperature?
1. Which biome is this and where is it located?
2. Which month(s) is the hottest? Coldest?
3. Which month(s) are the driest? Most moist?
4. Are there seasons?5. Is this near the equator,
north, or south of it?
Example
Temperate Forest
Tropical Savanna
Temperate Grassland
Chaparral
Desert
Tundra
Climatogram Activity You will be given a blank data page to look
at, with one set of data highlighted.
You will be given 2 markers – follow instructions to graph your climatogram
Answer the questions about your climatogram on the back of your sheet.
