HABITATS
SOL 3.6
WHAT IS A HABITAT?
The place where an
animal or plant lives
and grows: a home.
 Everything around a
plant or animal is its
habitat.

WATER HABITATS
They are animal homes
that are in the water such
as the ocean, streams,
rivers, swamps, ponds.
 Water related
environments( aquatic)
include those with fresh
water or salt water.
 Example include ponds,
marshes, swamps,
streams, rivers, and
oceans.

FRESH WATER
It is water that has
very little salt in it.
 Lakes, rivers, ponds,
and some marshes
are freshwater
ecosystems.
 We drink fresh water.

SALT WATER
It is water that has a lot of
salt in it.
 Oceans and seas contain
salt water.
 The oceans are Earth’s
largest ecosystem in size.
 There are many kinds of
animals and plants living
in salt water.

LAND HABITATS
animal homes that are
on the land such as
tundra, grassland,
desert, tropical rain
forest, and forests (
coniferous, and
deciduous).
 They are dry- land
environments(
terrestrial).

DESERTS









They are areas that get very little rainfall.
Deserts are land communities which can
be hot or cold with very little water.
In hot deserts the most often seen plant
is the cactus.
A desert plant has:
- a thick skin
- a thick stem
- very shallow roots
- and spine like needles
Jack rabbits, tortoises, rattlesnakes,
lizards, roadrunners, and coyotes are the
common types of animals.
TUNDRA



The tundra area has
the smallest
population of plants
and animals on earth
because of the short
growing season and
cold conditions.
Very small plants grow
there and little or no
trees.
Animals such as the
reindeer and polar
bears live here.
GRASSLANDS
The grassland area is a
flat area with few trees
and lots of tall grass.
 Animals that live in
herds and are herbivores
such as cows, buffaloes,
deer, zebras, antelopes
and giraffes live in this
area.
 Predators like the lion
live also here.

FOREST



An area in which
the main plants
are trees.
There are many
animals living
there, too.
Forests need rain
and sunshine,
and very high
temperatures.
TROPICAL RAIN FOREST







This forest is hot, humid, and
rainy with many trees and green
plants.
It has the largest population of
animals and plants. All types of
animals live there including
many insects and amphibians.
It has three main layers, where
animals and plants make their
own homes. They are:
- the canopy- or top part,
- the understory- below the
canopy
- the forest floor- the lowest
layer.
Trees are very tall, and they
have pole like trunks.
COASTAL FOREST
They grow where there
is a lot of rain.
 It does not get too
warm or too cold in
there.
 It has a lot of very tall
thick trees.
 It has the same layers
as in the tropical rain
forest.

DECIDUOUS FOREST









Forests that have trees whose leaves
- change color and fall off in the fall,
- die in the winter,
- bloom in the spring,
- and stay in the trees in the summer.
A forest of trees that lose and re-grow
their leaves each year.
We live in a deciduous forest.
Some of the animals living here are:
insects, snakes, birds, deer, and bears.
There are ferns, shrubs, and mosses, too.
CONIFEROUS FOREST






It is a forest of trees that forms seeds in
cones.
The main type of trees are conifers.
Trees are shaped like triangles so that
snow falls off.
Their leaves are shaped like needles
and they stay green all year round. .
For that they are called evergreen trees.
There are many lakes and streams
which provide habitat to squirrels,
moose, and wolves. There are some
insects, too.
WHAT IS AN ECOSYSTEM?

An ecosystem is all the living and non-living
things that interact together in a specific
environment.
WHAT IS POPULATION?
A POPULATION IS A GROUP OF THE
SAME KIND OF LIVING THINGS THAT LIVE
IN THE SAME PLACE AT THE SAME TIME.
Examples of a population are:
 - a group of swans in a pond,


- a school of fish in a river,

- and a herd of cattle in the grassland.
WHAT IS A COMMUNITY?

A community is all the populations that live
together in an ecosystem.

An example of a dry-land community would be
a forest made up of trees, squirrels, worms,
rabbits, and hawks.

An example of a water-related community
would be an ocean made up of fish, crabs, and
seaweed.
WHO WILL SURVIVE? HOW CAN WE HELP?
Organisms compete for the
limited resources in their
specific environment.
 Humans need to help
conserve limited resources.
 Can you list ways that
humans can help conserve
limited resources?



We can:
stop over harvesting species,
such as elephants, rhinos,
and tigers, leopards and
other big cats;

stop destroying habitats;

stop polluting and otherwise
disturbing habitats; and

stop spreading non-native
species(plants that originate
elsewhere and are brought
into a new area)
Ice Plant (Carpobrotus edulis) is
an extremely invasive species
from South Africa.
