9. THE WORD
ECOSYSTEM
It comes from ECO(home in
Greek)
ECOLOGY is the study of the
relationship between living
things and their environment.
And SYSTE
MA system is made up of parts that
form a whole.

10. 1.-DEFINITION OF ECOSYSTEM
An ecosystem is a community
of living things and non-living
things that interact in the
same place.

11. *Living things like animals,
plants and microorganisms.
*And non living things
aspects of the environment like
water, light, soil and
temperature.

12. 2.- TYPES OF ECOSYSTEMS
2.1. - AQUATIC ECOSYSTEMS
Aquatic ecosystems are found in
water. Rivers, lakes, seas and
oceans contain aquatic
ecosystems. There are two types:
Fresh water or salt water
ecosystems.

13. 2.2.- TERRESTRIAL
ECOSYSTEMS
Terrestrial ecosystems are found on
land. Deserts, forests, tundra and
grasslands are the main terrestrial
ecosystems.

14. 2.3. - MIXED ECOSYSTEMS.
These ecosystems combine
elements from aquatic and
terrestrial ecosystems, like ponds,
swamps and beaches...

15.  TRUE OR FALSE
 *Tundra Ecosystems are in the Artic Circle.
 *The living things that you can find in a Pond Ecosystem depend
on the type of shore.
 *There is Little biodiversity in the Beaches Ecosystems because
there is too much salt water.
 *We can find the same aquatic plants or animals in all Oceans.
 *There are more evergreen trees than deciduous trees in the
Forest Ecosystems.
 *Lakes Ecosystems contain water all year.
 *The species that inhabited a River Ecosystem depend on the
water temperature.
 *In Desert Ecosystems there is more evaporation than rainfall.
 *In Grassland Ecosystems there is a lot of rainfall.

16. 3. The elements of an ecosystem.
It consists of living things ,a
habitat or physical environment
and the relationship or
interaction between living
things.

17. 3.1.1 Living things in a
ecosystem.In an ecosystem there are many different living things, such as ___plants _ and
__animals_.
Why are some butterflies different from each other? Because they are members
of
two different ___species______.
SPECIES consist of a ____group_______ of organisms that reproduce among
themselves.
Members of the same species possess ______similar __ characteristics.
They often appear and ______behave_______ similarly. A group of the same
area
is called a _____population______
All these different populations of living things make up a ___community_____

18. Living things in each ecosystem
have certain characteristics
called adaptations, which permit
them to survive in that
ecosystem.

19. How have these animals these
adapted to their environment?

20. POLAR BEAR-
LIVES IN THE ARTIC ECOSYSTEM.
 Has white fur for
camouflage.
 Has a layer of fat
under fur for extra
insulation.
 Has sharp teeth and
claws to catch and
eat prey.
How is a Polar bear suited to its ecosystem?

21. CAMEL- LIVES IN THE DESERT
 Can close nostrils to
keep out sand.
 Has long eyelashes
to keep out sand.
 Can store fat in
hump and go for
long periods without
water.
How is a camel suited to its ecosystem?

22. PENGUIN- LIVES IN THE ARTIC
 Has thick layer of fat
to keep warm.
 Produces oil to keep
feathers waterproof.
 Stream lined body
for swimming.
How is a penguin suited to its ecosystem?

23. CACTUS- LIVES THERE.
 Can survive a long
time without water.
 Has sharp spikes for
protection.
 Has long roots to
collect water.
How is a cactus suited to its ecosystem?

24. ACTIVITY FOR THE NOTEBOOK.
WHAT ECOSYSTEM DO THESE
LIVING THINGS INHABIT?
HOW IS A Penguin, Camel, Cactus, Polar bear SUITED TO ITS
ENVIRONMENT?

25. HOW IS A POLAR BEAR SUITED TO ITS
ENVIRONMENT?
 It lives in an Artic
Ecosystem.
 It has sharp teeth
and claws, to
catch and eat
preys

26. 3.2 HABITATS.
 The place where
an animal or living
thing lives is
called its habitat.
 An animal lives
when it can find
food, water and
shelter.

27. 3.2.1 CHARACTERISTICS HABITATS.
 Oceans- cold, salt
water, many
predators.
 Artic- Very cold,
snow and ice, little
shelter.

hot , humidity,
many plants and
trees.

28. 3.2.CHARACTERISTICS HABITATS.
 Woodland- can be
cold in winter, many
plants and trees.
 Meadow- little
shelter, lot of grass
to eat.
 Mountains- very
cold higher up, little
shelter

29. 3.2.CHARACTERISTICS HABITATS.
 Swamp -Damp,
marshy with many
different plants.
 Desert – very dry,hot
in the day, cold at
night, little shelter.
 Pond/lake.-Sheltered
water is calm, many
plants.
