* THE RELATIONSHIPS OF ECOSYSTEMS
* THE CONSERVATION OF THE
ECOSYSTEMS
* THE WORLD WE WANT

4. SAUCE PICAPINOS
EACH LIVING BEING LIVES IN A PLACE WHERE
YOU CAN MEET YOUR NEEDS

5. ECOSYSTEMS
AN ECOSYSTEM IS A NATURAL SYSTEM CONSISTING OF:
• LIVING THINGS: PLANTS AND ANIMALS
• THE PHYSICAL ENVIRONMENT: TEMPERATURE,
WATER, SOIL, ROCKS...

6. TYPES OF ECOSYSTEMS :
TERRESTRIAL ECOSYSTEMS
FOREST PRAIRIE DESERT
AQUATIC ECOSYSTEMS
FRESHWATER SALT WATER

8. RELATIONS
among living things in an ecosystem are
given different relationships:
 relations of power
 competitive relationship
 cooperative relationships

9.  in ecosystems
producers: plants make their own food.
consumers
primary: herbivores animals
 secondary: carnivorous animals

10. Herbivores animals
• herbivorous animals feed on plants
giraffe
Deer

11. Carnivorous animals
• carnivorous animals eat other animals
Chameleon
Leon
Snake

12. food chains
• the food chain is the way to represent the mode in
which is feed on living things in an ecosystem
producer primary consumer secondary consumer

13. LINKS OF FOOD CHAINS
• EACH ANIMALS CHAIN DEPENDS ON ANOTHER
LIVING BEING TO FEED.

14. COMPETITION
• THE LIVING BEINGS COMPETE WHEN
THEY HAVE A NEED.
• PLANTS COMPETE FOR SUNLIGHT, GROW
MORE QUICKLY.
• ANIMALS COMPETE FOR FOOD,
TERRITORY.

15. THE COOPERATION
• THE COORPORACIÓN OCCURS WHEN TWO LIVING
BEINGS ARE COLLABORATING AND WILL BENEFIT

16. CONSERVATION OF
ECOSYSTEMS

17. • :
ECOSYSTEMS ARE IMPAIRED
ECOSYSTEMS ARE IMPAIRED BY
• POLLUTION
• DEFORESTATION
• OVEREXPLOITATION

18. pollution can
affect water, air
and soil
among the causes
of pollution are
waste and smoke

19. REDUCE CONTAMINATION
using clean transportation
depositing trash in proper
containers for recycling

20. The deforestation
deforestation is the
loss of forests for
timber or crops
when forests
disappear, disappear
also the animals that
inhabit

21. THE EROSION
trees are cut when the
ground is bare and the
rain and the wind drag the
ground.
soil loss is called erosion
and damages the
ecosystem even more

22. the overhunting
overexploitation occurs when
an ecosystem take more
animals or plants they
produce.
an example is tuna fishing has
endangered the survival of
spice
ecosystem protection
ecosystems are protected by the
laws of the declaration space-
protecting national parks as an
example of this is the park closes
