Habitats
What are they???
A habitat
is where things live.
It’s more than a home it’s more like a
neighborhood
For an animal a habitat includes all the
land the animal needs to hunt gather
food find a mate and raise a family
pictures of different habitats:
Biotic diversity
This just means how many different
species of living things (plants and
animals) there are in a particular area.
HIGH Biotic
diversity- LOTS of
different species
live there
Tropical rainforests have HIGH biotic
diversity
LOW biotic diversity- NOT
VERY MANY different
species live there
tundra has LOW biotic diversity
Biotic Factor- Any
Factor that is living or used
to be living and
in a biome
(animal or
plants) ex. A
tree, a rotting tree
stump, a dead and
decaying squirrel
ABIOTIC
FACTOR- any thing
not living that is
present in a biome. Ex. Air, water,
sunlight, soil
Some important “BuZZ”Biomes…
That they always expect you to know
A reminder about Biomes:
Biomes A biome is a large ecosystem where
plants, animals, insects,
insects, and people live in a certain type of climate.
Coniferous Forest or Taiga - These
forests you’ll find just south of the frigid tundra. They have
trees with cones such as spruce, hemlock, and fir,
which do very well in the cold climate and low
precipitation. The soil is not very fertile. Some animals
that thrive or do well in this biome are the moose, the red fox, the
snowshoe rabbit, the great horned owl.
Deciduous forest-
These areas
have trees that lose their leaves in the fall. The
soil is rich and
and supports a lot of plant and animal life. Trees that
live here are oak and maple. Animals that live here are raccoons,
squirrels, mice, rabbits, deer and cardinals.
Grasslands-
Have hot
dry climates that are
perfect for growing food. They have a lot
lot
of names depending on where you are…in the U.S.U.S.prairies, in Africa and South AmericaAmerica- Savannas, and
parts of Europe and AsiaAsia- Steppes. It’s very
grassy here, not enough rain for trees. A very small
variety of animals.
Tropical RainforestsAre areas
areas that get high amount of rainfall per year. The
climate of a rain forest is very hot and humid . Tropical
Rainforests are found closer to the equator.
Rainforests have a more than ½ of the world’s
total plant and animal species…For this reason
they are said to have HIGH BIOTIC
DIVERSITY!
Mountains (special
mention)-
Mountains are found usually as
a chain of mountains. Sometimes they stand alone. This
biome is very cold and windy. The higher
you are on a mountain, the colder it is and also less oxygen
oxygen
at these higher elevations. Usually no
trees
growing at the tops of mountains. Forests can grow at
the bottom. Animals that live on high mountains are used to low oxygen and cold temps.
Climatographs
Climatographs are often used to represent a
location’s temperature and precipitation
patterns.- as a reminder, climate is an area’s temperature and
precipitation.
(Precipitation (how much water)water)- is measured with the bar graph.)
(Temperature(Temperature- is measured with the line graph)
This climatograph represents a
tropical rainforest.
Pay attention to the different
scales. The Precipitation scale is
on the left in (mm). For
precipitation, look at the bars.
The Temperature scale is on the
right in (°C) - that’s Celsius. By
The Climatograph measures precipitation and temperature in
a biome. The letters at the bottom represent the months of
the year.
the way…the Celsius scale is
NOT the (°F) Fahrenheit scale
that we use.
(80°F –is a really warm day for us. On the Celsius scale
80°F is 27°C. 27°C might seem cold if you’re just looking
at the number. It’s actually a WARM temperature!)
Food
Webs
Food webs show us how different species
interact in a specific ecosystem.
Arrows point to who’s doing the eating
There
are
usually
several organisms that
eat the same thing.
This
causes
COMPETITION
between the organisms
Food Chains and Food Webs
Producers also called autotrophs, make
their own food
Consumers also called heterotrophs, Have to
eat other things to get energy
Herbivores
Eat
only
plants
Some examples of plant only eaters
Carnivores Eat only meat
Lions are carnivores
Omnivores Eat plant and meat
Humans and Bears
are omnivores
Decomposersbreak
Earthworms and
bacteria break
down dead things
Detritivores-
down things that die
SCAVENGERS that feed on dead things.
They wait
on things to die and then they eat them
A vulture is a detritivore. You see this
one eating a dead animal
Look at the different consumer levels in a food chain
Energy flow in an ecological
pyramid
Energy in any
system flows from
the producers to
the consumers
Only 10% of the
energy is available
from the previous
level (the level the
consumer is eating
from)
ECOSYSTEMS
WHAT ARE THEY????
The plants and animals that are found in a particular
location are called an ecosystem.
These plants and animals
depend on each other to
survive.
Disruptions (means something
to mess stuff up) to an
ecosystem can be disastrous
(means really bad) to all
organisms within the ecosystem.
Thes an ecosystem. These plants and animals depend on each other to
What happens when a new plant or animal
is introduced into an ecosystem, where it
did not before exist. The new organism competes
with the natural organisms from that location for available resources. These
