- 4.4 BIOMES Regional climates: For example~ a state or country
with a ocean borderign it is involved in a cold ocean current that
flows north to south, which makes summers cooler. Moist air will
travel and expand to make clouds. Rain or snow will drop from the
clouds to change the weather pattern
- Slide 3
- BIOMES Groups of regional climate communities described in
terms of the abiotic factors like: Climate Soil type And biotic
factors like: Plants Animals
- Slide 4
- CHARACTERIZED BY The adaptations that allow them to survive and
reproduce.

- TROPICAL RAIN FOREST A tropical rain forest is home to more
species than any other biome As you would probably guess from name
they do get a lot of rain At least 2 meters a year
- Slide 7
- CANOPY Dense layer formed by tall leafy trees clustered
together everywhere Range from 50 to 80 meters tall above forest
floor
- Slide 8
- UNDERSTORY Smaller trees and vines under the canopy form this
layer
- Slide 9
- 2 ABIOTIC FACTORS AND 2 BIOTIC FACTORS 2 abiotic would be that
its hot and wet year round and there is nutrient poor soil 2 biotic
factors are the plant and animal life
- Slide 10
- 4.4 Biomes (Tropical Dry Forests)
- Slide 11
- Tropical dry forests Tropical dry forests grow in areas with
rainy seasons alternate with dry seasons. In some cases after a
period of rain is instantly followed by prolonged periods of
drought.
- Slide 12
- Abiotic factors Tropical dry forests are warm all year round,
and have rich soils that are subject to erosion.
- Slide 13
- Biotic Factors Plant Life: plants have adapted to survive the
dry seasons by loss of leaves. Plant Life: Some plants also have an
extra thick waxy layer over their leaves to lower water loss and to
store water in their tissue.
- Slide 14
- Biotic factors ( Continued ) Animal Life: to survive the dry
seasons animals can reduce their needs for water by entering long
periods of inactivity called estivation. Other animals including
many birds and primates move to the areas where water is available
for them during a dry season.

- ANSWER 1: DECIDUOUS ANSWER 2: PLANT LIFE, ANIMAL LIFE What is a
plant that sheds its leaves during a specific season? What are the
two biotic factors of tropical dry forests?

- Slide 18
- Tropical Grassland/ Savanna More rainfall than deserts but less
than tropical dry forests Grassy area usually with trees and shrubs
Frequent fires Action of larger animals sometimes prevents area
from turning dry IE: rhinoceroses and elephants
- Slide 19
- Abiotic and Biotic Factors Abiotic Seasonal rainfall Fires set
by lightning Biotic Plant life (adaptations) Animal life
(migration)
- Slide 20
- Desert Less than 25 centimeters of rain annually Deserts
undergo extreme daily temperature changes 100 F during the day to
under 30 F at night
- Slide 21
- Abiotic and Biotic Factors Abiotic Low rainfall Soil rich in
minerals but low in organic material Biotic Plant life (cacti)
Animal life (avoid heat, get water)

- Section 4.4 #s 57-60
- Slide 23
- Grasslands are areas where the vegetation is dominated by
grasses. Temperatures dont get too hot or too cold
- Slide 24
- Abiotic factors- non-living tings that shape an ecosystem.
Examples- warm to hot summers; cold winters; moderate sea soil
precipitation, fertile soils; occasional fires.
- Slide 25
- Biotic factors- living things that shape an ecosystem.
Examples- grasses and birds.
- Slide 26
- Abiotic factors- non-living things that shape an ecosystem.
Examples- hot bry summers; cool moist winters; thin, nutrient- poor
soils; periodic fires.
- Slide 27
- Biotic factors- living things that shape an ecosystem.
Examples- plants and white-tailed deer.

- 4.4 Temperature forests Clayton welch
- Slide 29
- Conifers Conifers produce seed bearing cones. They have leaves
shaped like needles. Waxy substance reduces water loss. Soils are
rich in humus, formed from decaying leaves and other organic
matter.
- Slide 30
- Abiotic factors Cold to moderate winters. Warm summers Year
round precipitation Fertile soils
- Slide 31
- Biotic factors Plant life- Deciduous trees. Animal life-
Animals cope with changing weather others migrate to warmer
climates. Animals that do not migrate may use camouflage to escape
predators in the winter when bare trees leave them exposed
