Transcript Biomes

Biomes
Think back to ecosystems….
Individual- 1 specific
organism
Population- all of 1 type
of living organisms
Community= Only the
living factors
Ecosystem= Living and
non living factors
Biome= Ocean
Biosphere= Earth
What are biomes?


Biomes are large regions of Earth.
Each biome has a certain kind of climate.
Different communities of living things are
found in different climates.
Earth’s major biomes




Earth has six major biomes.
Write:
A biome is a large group of
ecosystems that are similar is
some ways.
The major difference is climate.
World Biomes






Tundra
Taiga
Temperate Forest
Tropical Rain Forest
Grassland
Desert
Think of some organisms
that you might find in a
desert….





Deserts are the home to many
living things. In fact, deserts are
second only to tropical rainforests
in the variety of plant and animal
species that live there.
How do you think plants grow in a
place that is very, very dry?
Many of the fascinating features
of desert plants are adaptations -traits that help the plant survive in
its harsh environment. Desert
plants have two main
adaptations:
Ability to collect and store
water
Desert plants often look different
than plants in any other biome.
Think of some organisms
that you might find in a
grassland biome…


Grassland biomes are covered
with grasses, have very few trees,
and have long periods with no rain.
Two examples are prairies and
savannas.
Think of some organisms
that you might find in a
forest biome…
There are two types of
forest biomes



Temperate forests- have four
different seasons: summer, fall,
winter, and spring.
It has animals such as deer, rabbit,
skunks, squirrels, and bears.
Trees in these forests lose their
leaves in the fall.
Temperate forest food chain
Rainforest biomes





Very rainy and hot.
Some get more than (240 in.) of
rain each year!
This makes it summer all year.
There are also numerous types of
insects.
Ecosystems can be as small as a
puddle.

Taiga




Taiga biomes have long,
harsh winters and short,
cool summers.
The taiga is dry.
Most of the precipitation
is snow.
Most of the trees are
pines, firs, and spruces.
Gray Wolf
Tundra
The tiaga’s climate is mild
compared to the tundra.
 The tundra is the Earth’s
coldest biome.
 The lower layers stay
frozen all year long.
 It has an average
temperature of
(-29 degrees F)

Tundra food pyramid

Inches of rain fall per year.
Marine Biomes


Oceans cover 70 % of Earth.
In the oceans are marine biomes.
Freshwater Ecosystems


Many bodies of water are made up
of fresh water.
Streams, rivers, ponds, lakes, and
wetlands are freshwater
ecosystems.
For Homework
Choice one of the biomes mentioned
in this power point.
 Come up with a few organisms living
within the ecosystem (of your choice
of biome) that would make a food
chain.
 Draw and color them.
In one to two paragraphs tell how the
following will affect the organisms
within the ecosystem.
 1. A drought occurs
 2. Continuous rainfall

