2. Environmental Systems Project
• Work together in your groups to
complete this
• Each group is assigned a specific
Biome to research
• You will be researching the information
using textbooks and the internet – use
them properly!!
• Final project will be presented on a
poster to the class
• Completed and due by THURSDAY!

3. Every group must start their research using the
textbook.
• There is information on each biome from pages
68-79
• The 3 active computers in the room can be used
as well- the two by the windows, and this one
• 5 minute maximum per group- decide what
you will be looking for BEFORE you get on
the computer!

5. •A biome is an area of the planet that can be
classified according to the :
*Plants
*Temperature
*Precipitation
*Animals
*Soil

6.  Temp: winter -54 to -1° C
(-65 to 30° F)
summer -7° to 21° C (20°-
70° F)
 Precipitation: 30-85 cm
/year
Taiga

7. Red Fox
Uses its tail as a cover in
the winter
Long Eared Owl
Can see a field mouse from 100 yards
away (at night!)
Taiga

8.  Temp: 20oC (68oF) - 25oC (77oF)

*as many as 50% of all the
world’s animal species may be
found here
Tropical Rainforest

Stores fluids to feed the colony

12.  Temp: –30oC (-22oF) - 30oC (86oF)
 Precipitation: 75 - 150 cm/year
 Most trees lose their leaves in the winter
Temperate Deciduous Forest

13. Bald eagle
Eyesight is 4X that of a human with
perfect vision
Fire salamander
Releases poisonous neurotoxins
Temperate Deciduous Forest

14.  Temp: Winter –34oC (-29oF)
Summer below 10oC (50oF)
 Precipitation: 15–25 cm/year (Low
precipitation)
*low dversity
* permafrost (permanently frozen soil)
Tundra

15. Japanese snow monkey
Bathes in hot springs
Lemmings
White in winter, brown in summer
Tundra

16.  Temp: Summer up to 38oC (100oF)
Winter down to –40oC (-40oF)
 Precipitation: 50cm - 90 cm/year
Grassland

17. African Wild Dogs

Grassland

18.  All areas that are under water
 Includes: freshwater/saltwater
warm/cold
deep sea/shallow pond
Aquatic

19. Planaria
Regenerative properties
Protoperidinium pellucidum
Pytoplankton make up 90% of marine
biomass
Aquatic

20. Portuguese Man of War
Not a jellyfish!!!!!
Made up of a colony of organisms
working together (zooids)
Southern Right Whale
Dolphin
Has lost dorsal fin through evolution
Aquatic

21. Threats to Biodiversity
• Human activities decrease biodiversity and the
ecosystem’s stability:
1. Habitat alteration 3. Pollution
2. Improper hunting 4. Invasive species

22. 1. Habitat Alteration
• Changing or altering a habitat
• Ex. Habitat fragmentation
-organisms isolated from resources
- organisms isolated from mates
-increased deaths

23. 3. Pollution
a substance or thing that has harmful or poisonous
effects on the environment
• Water pollution (acid rain)
• Air pollution (carbon dioxide)
• Soil pollution
• Noise pollution

24.  Oceans flow over nearly three-quarters of our planet, and
hold 97% of the planet's water. They produce more than
half of the oxygen in the atmosphere, and absorb the most
carbon from it.
3. Pollution

25. 4. Invasive Species
nonnative species that disrupts the native
species.
• Usually transported to new habitat by humans.
• Lacks predators and competition
Ex. Kudzu is a climbing vine that was introduced to the U.S. in the late
1800s to control erosion. It quickly took over parts of the landscape,
displacing the plants that used to grow there.
