Monday 9/22/14
• Homeroom warm up
• Write the definition of the word of the week
in your own words.
Monday 9/22/14
• Warm Up
– What effect does environment have an
organisms?
What is a Limiting Factor?
• Limiting Factors are…
(two similar definitions)
– conditions of the
environment that
limit the growth of a
species.
– biotic and abiotic
factors that prevent
the continuous growth
of a population.
What is a Limiting Factor?
• Populations would continue to increase if
they had all of the resources they require in
unlimited amounts, but there are always
factors that limit their increase.
• Limiting factors control
population growth.
Let’s list some Limiting Factors!
 Food
Water
 Shelter
Space
Homework
• KIM Chart for vocabulary words of the week.
• Vocab #4 quiz Friday
What is Carrying Capacity?
• Because of these limiting factors, each
ecosystem has a finite capacity for growth
connected to its carrying capacity.
What is Carrying Capacity?
• Carrying capacity is
the number of
individuals of a
species that an
ecosystem can
support.
Summary
• In nature, populations of organisms rarely grow
uncontrolled. Each ecosystem has a carrying
capacity (or number or organisms it can
sustain/support).
• Remember, limiting factors are biotic and abiotic
factors that prevent the continuous growth of a
population.
• Because of limiting factors, the number of
organisms in a population is often well below
carrying capacity.
GIZMO
• Please login into www.explorelearning.com
• Use login and password that Ms. Lucich gave
you.
• Begin Gizmo
T.O.D
• Give an example of limiting factor and carrying
capacity that are related.
Tuesday 9/23/14
• Homeroom Warm Up
• Write a paragraph using the word of the week.
Biome Map
What are Biomes?
Biomes are regions in the world that share
similar plant structures, plant spacing,
animals, climate and weather.
How are Biomes Classified?
Biomes are classified as either terrestrial or
aquatic. Terrestrial means Earth and
Aquatic means Water.
How Many Biomes Are There?
Scientists disagree over the exact number of
biomes, but in general they include around
8-10 biomes.
Tundra
•
•
•
•
•
•
•
Very cold
Permafrost- frozen soil and rock year round
Low diversity of animals and plants
No tree growth, Simple vegetation
Short growing season
Plants-mosses, grasses and lichens
Animals-musk ox, reindeer, wolves and owls.
•
•
•
•
Desert
Dry and very little rain
Animals are small
Many animals are nocturnal.
Dessert animals include lizards, scorpions,
desert rats, insects, hawks and jackrabbits
• Temperatures can be very hot or very cold
• Plants are adapted to conserve water, like
cacti
Coniferous Forest
•
•
•
•
Also called the taiga or boreal forest
The largest terrestrial biome
Temperatures are low
Precipitation is primarily snow in winter and rain
in fall and spring
• Soil is nutrient poor and acidic
• Flora is mostly coniferous, or cone-bearing trees
(pine, fir, hemlock and spruce have needleshaped leaves)
• Animals include woodpeckers, hawks, moose,
bear and lynx.
Decidious Forest
• Temperature varies
• Soil is rich with decayed matter
• Plants consist of broad leave trees that
loose leaves in fall.
• Includes animals such as squirrels,
rabbits, skunks, and bear.
• Even precipitation throughout the year
Tropical Rain Forest
•
•
•
•
Located at or near the equator
Very rainy and warm
Little variation in climate
Highly diverse species (about 75% of
earth’s land species live in rain forests)
• Tall trees with broad leaves that form a
canopy of vegetation
• Wide variety of insects, snakes and
lizards, colorful birds, monkeys and apes
• Soil is nutrient-poor and acidic
Grasslands
There are two types of grasslands. The tropical
grasslands (savanna) and the temperate
grasslands (prairies).
Dominated by grasses and very small number of
trees, moderate rainfall and rich fertile soil.
– Savanna’s have hot summers, cool winters, a
wet and dry season
• Support large herbivores such as
elephants, giraffes, zebra and buffalo. Also
support large carnivores such as lions and
hyenas
– Temperate grassland (prairies) has a hot
summer and cold winter
Mountains
• Different climates than surroundings
• Warmer at base and colder at high
levels (various biomes can be present
on a mountain)
• Less oxygen at high levels
• Rugged landscape
• Mountains normally can have a dry
side and a wet side (moist wind
travels from one side to other)
Marine Biome
• Consists of oceans and coral reefs
• The ocean is the largest of all ecosystems.
• The ocean contains a diverse array of plants
and animals at various depth zones.
• Coral reefs consist mainly of coral.
Freshwater Biomes
• Includes ponds, and lakes; streams and rivers,
and wetlands.
• Ponds and lakes have well lit zones and a
variety of fish dominate this zone.
• Streams and rivers move in one direction.
• Wetlands are areas of standing water that
support aquatic plants.
Estuaries
• Estuaries are areas where fresh and salt
water environments converge. Mangroves,
oysters, crabs, worms, water birds and
marsh grasses are examples of species in
this environment.
• Also known as inlets, bays, harbors and
lagoons
Tuesday 9/23/14
• Warm Up – How does a change in
temperature and/or precipitation effect living
things in their environment?
• Learning Targets for today:
• I will be able to identify and explain the
difference between a terrestrial and aquatic
biome
Cornell Notes for Biomes
• Please take a piece of paper out and take
Cornell notes on the Biomes.
T.O.D
• Write 3-5 sentence paragraph explaining what
you learned about biomes today.
• Please bring colored pencils to class
tomorrow.
