Biodiversity refers to all living things in an ecosystem. It allows ecosystems to support life and recover from environmental changes. An ecosystem consists of biotic and abiotic components that interact and depend on each other. However, biodiversity and ecosystems are threatened by human activities like habitat destruction, pollution, and introduction of invasive species. Biodiversity plays an important role in ecosystems by providing habitats, food sources, nutrient cycling, pollination, and other essential functions. While human activities pose the greatest threats, individuals can help protect biodiversity through practices like recycling, reducing pollution and carbon footprints, and sustainable consumption.

1. Biodiversity and ecosystems
By Vumboni Harry Msimango

2.  Biodiversity is the term that is used to
describe all the living things in an
ecosystem.
 Biodiversity's importance in ecosystems
is that it (Biodiversity) allows
ecosystems to support life and to
recover from changes to the
environment.
Biodiversity

3. ecosystem
 An ecosystem is made up of a particular
area and its living (biotic) and non-living
(abiotic) components.
 It is specifically a system whereby both
living and non-living components
depend on one another and constantly
interact with each other.

4. Biodiversity and
Ecosystems
 Both our Biodiversity and Ecosystem is
being threatened by the biggest threat
us, humans
 We destroy their habitats we throw
stones at even the smallest or cutest
animal because of our insecurities.

5. Threats to biodiversity.
 Alien Species
 Poaching
 Pollution
 There are many factors that threaten
biodiversity are natural disasters like
floods and fires. But most of the threats
are from humans, this is a direct result
of the massive growth of the human
population.

6. Threats 2
 Oil pollution
 When there are oil spills from oil tankers
thousands of birds become covered in in
oil.
 Luckily there are organizations like
SANCCOB that volunteer to provide
food and to clean the birds.

7. Habitat destruction.
 The biggest human threat to
biodiversity is habitat destruction. Most
living things need stable undisturbed
habitats.
 We disturb and change habitats by
doing things such as cutting down
indigenous forests , filling in wetlands,
damming up rivers and clearing land for
new settlements, golf courses and
roads.

8. Threat 3 alien Species
 Alien species are plants and animals
that originally comes from other
countries
 People often bring alien species into
new areas either on purpose or by
accident.
 But the problem is that of alien plants
grow faster than indigenous plants

9. alien species
 Adding to the problem is
that there are often few
or no natural predators
or diseases to keep the
plants and animals in
check
 There also alien animals
I'm familiar with the alien
bass (type of fish)
according to my research
in rivers and dams they
prey heavily on
indigenous fish

10. pollution
 Throughout the whole world rivers,
dams and lakes are polluted with wastes
produced by humans
 Plastic pollution in rivers is the worst
because plastic does not breakdown
naturally or biodegrade.
 Our biodiversity is in danger because of
us human beings.

11. Cats
 Cats are also
considered to be
threats to our
ecosystems because
facts state that cats
have killed over 1
billion small animals
such as birds and
rodents
 Their lack of predators
means that most will
live long lives and
continue to kill.

12. Cats 2
 So next time you see a
cute cat, look again and
don't be fooled. It is an
expert hunter and poses
major problems to the
ecosystem.

13. The importance of biodiversity
in ecosystems.
 Biodiversity allows ecosystems to
support life and to recover from changes
to the environment
 Biodiversity in ecosystems is important
in the following ways

14. habitats
 Forests and
wetlands provide
habitats for many
types of animals.

15. Food
 Plants form the base
of all food chains.
 Herbivores feed on
plants and
Carnivores feed on
herbivores.

16. Clean air
 Through
photosynthesis
plants provide
oxygen for
respiration and
regulate the levels
of carbon dioxide in
the atmosphere.

17. Soil nutrients
 Decomposers such
as worms play in
important role in the
nutrition process of
enriching the soil.

18. Wetlands
 Wetlands act as
water filters that can
trap pollution and
contribute in a much
amazing way of
being a habitat and
a feeding area of life
stock.

19. Pollination
 Most different plants
are pollinated by
animals such as
bees and butterflies.
 This also helps for
plants to advance
their growth but it is
also a disadvantage
if the pollination is
taking place in alien
species.

20. Water cycle
 Trees play an
important role in
forming rain clouds
through evaporation
of water from their
leaves.

21. Preventing Soil erosion
 Plants are vital for
preventing soil from
washing away and
causing soil erosion
which is good for
helping animals not
to get washed of or
getting hurt.

22. Threats to global
biodiversity
 This is a pie chart
showing the known
causes of animal
extinction but all this
causes have one
thing in common all
this extinctions are
caused by humans.

23. Biodiversity in Ecosystems
 Al the 8 slides that I have shown are just
a way of showing a way in which
biodiversity is important in ecosystems.
 But we to as the biggest threat can also
contribute in the safety of our
biodiversity and ecosystems.

24. How we can protect our
ecosystems.
 By :
 Recycling
 Using eco-friendly products
 Reducing our carbon footprint
 Choosing foods that are locally grown and
grown sustainably.
 Poaching can be used at a certain extent
like for instance on the cat case they are
quite many so there is a need for them to
be hunted.

25. Conclusion
 People we are biodiversity's biggest
threat but we can also be biodiversity's
biggest helper we can contribute to the
revival of both our ecosystems and
biodiversity instead of causing
destruction lets help maintain our nature
and natural resources.

26. The end
LET US HELP MAINTAIN OUR NATURAL CAUSES
BIODIVERSITY IS ALREADY PLYING ITS CAUSE IN
OUR ECOSYSTEMS LETS CHANGE OUR FUTRE
FOR THE BEST THANK YOU.
