BIOMES: A quick REVIEW
Earth’s Biomes: groups of ecosystems with similar climates
and similar organisms. Plants included OF COURSE!
Why do you think
organisms are
similar in a specific
biome?
Wind
The uneven heating of the
Earth:
• drives ocean currents
• causes wind
and therefore affects Earth’s
climate regions.
Why is there uneven
heating of the
Earth?

| Latitude
and
Longitude
For example, the U.S. Capitol is located
at 38°53'23"N , 77°00'27"W (38
degrees, 53 minutes, and 23 seconds
north of the equator and 77 degrees, no
minutes and 27 seconds west of the
meridian passing through Greenwich,
England).

Biomes
Topical Rain Forests:
Warm temperatures that do not vary much
Very wet and humid
Greater variety of species than any other
biome
Temperate Rain Forests: Northwestern US, cooler
temperatures here
Desert:
Receives less than 25 cm of rain/year
Very dry
Hot during the day and cool/cold at night
Animals adapted to extreme temperatures
What adaptations do these animals have?
Grassland:
Also called a prairie
Receives between 25-75 cm rain/year
Populated by grasses and large herbivores (plant eaters)
What are some examples of large herbivores?
Savanna: Located closer to the equator and
receives more rain—up to 120 cm/year.
Why would you find larger trees in the Savanna?
Deciduous Forest:
Trees lose their leaves each year
Temperature varies during the year
Varity of plants
At least 50cm rain/year
Why would you have a
variety of plants here?
Boreal Forest: or Taiga
Colder climate than deciduous (very cold winters)
Trees with needles and cones
Snow in the winter
Tundra:
Extremely cold, very dry
Most of the soil is frozen all
year
Windy and only low growing
plants
What adaptations do the animals all have in common?
Freshwater:
Ponds and lakes (lakes are larger and deeper than ponds) “Standing”
Streams and rivers (animals must adapt to current) “Flowing”
Marine #1:
An estuary is shallow sunlit water where freshwater meets
ocean water and is often a breeding grounds for organisms.
Why do you
think many
animals breed
here?
Marine #2:
Intertidal Zone, Neritic Zone, Open Ocean Zone Surface Zone,
Deep Zone (all saltwater)
Photosynthesis takes place in the Surface Zone or Photic Zone
Intertidal
Deep Zone
Neritic Zone
..
Open Ocean
Why doesn’t
photosynthesis take place
in the Deep Zone?

Surface Zone (Photic Zone)
Deep Zone (Aphotic Zone)

Chemistry (What type of chemicals are present?)
Geography (rocky/sandy bottoms, reefs)
Light
(A lot or NONE so affects photosynthesis)
Depth
(changes light content and pressure…)
Salinity
(Salt affects living creatures big time)
Temperature (not too hot or too cold!)
