Science for Grade 6 Quarter 2 Protection and Conservation of Ecosystem

2. Protect and Conserve
Tropical Rainforest,
Coral Reefs and
Mangrove Swamps

4. Look and study figure for
Types of Ecosystem, these
are the 3 different kinds of
ecosystem namely Tropical
Rainforest, Coral Reefs and
Mangrove Swamps

5. Tropical rainforest, coral
reefs and mangrove swamps
serve as nurseries, breeding
places, and habitat of
economically important
plants and animals. They
provide resources and needs
for people.

6. As the human population
increases, the demand for the
use of these resources
increases, thus upsetting the
ecological balance. Our role
is to protect and conserve the
resources and the ecosystem
and practice sustainability.

7. In sustainability, it is simply
the wise use of the natural
resources.

8. Activity 1. 1 Why is there a
need to conserve living
things? Read and study on
Soil Conservation and on
Water Conservation, then
answer the questions below.
Write your answer on the
attached activity sheet no.1

9. Ecosystem Conservation
Human activities disturb and
destroy biodiversity and the
natural balance of the ecosystem.
Most of these activities alter the
structure and functions of both
living and nonliving components
of the ecosystem.

10. We need to give high value to
these ecosystems because they
provide us our needs for food
and shelter. The government
improved four different
strategies in protecting and
conserving that we should
practice.

11. Strategies in Protecting and
Conserving Ecosystem
A. Conserving the needs of
living things
B. Habitat Restoration
C. Wildlife Conservation
D. Protecting forest, Coral reefs
and Mangrove swamps

12. A. Conserving the needs of
living things
1.Soil Conservation
In soil conservation the top soil
is exposed which affects the
nutrient content of the soil. As
the topsoil disappears, plant
growth is affected.

13. Soil conservation involves
employing agricultural soil
management methods. Some of
the most effective methods
include:

14. Contour Farming

15. a. Contour farming
It is the planting of crops
along the contours of
sloping lands to minimize
erosion and runoffs.

16. Strip-cropping

17. b. Strip-cropping
- It alternates strips of
crop and uncultivated land
to minimize erosion and
water runoff

18. Terracing

19. c. Terracing
- It reduces erosions and
runoff on slopes

20. Figure 1.2 Water Conservation

21. 2. Water Conservation
-Restoring the vegetation
in the forest or watersheds
could increase the storage
of the filtering capacity of
watersheds.

22. Activity 1.1
Directions: Answer the following
questions.
1. What are the strategies in protecting
and conserving the ecosystem?
2. Give the three effective methods in
soil conservation.
3. What is contour farming?
4. How to conserve the watersheds?
5. Why should we conserve the soil?

23. Activity 1.2
Read and study on Ways of Habitat
restoration then answer activity 1.2.
B. Habitat Restoration
-It seeks to repair areas that have been
subjected to habitat destruction. There
are three ways of Habitat Restoration
namely: Building man-made fish
sanctuary, reforestation and mangrove
rehabilitation.

24. WAYS OF
HABITAT
RESTORATION

25. Building a man-made fish sanctuary

26. 1.Building a man-made fish
sanctuary.
-with the creation of fish
sanctuary. the marine
ecosystem has the chance to
be restored. In addition,
overfishing will be reduced

27. Reforestation

28. 2. Reforestation
- Replanting of trees will help
restore the forest ecosystem
and its wildlife.

29. Mangrove Rehabilitation

30. 3. Mangrove Rehabilitation
Includes the following:
a. Cancellation of existing fishpond lease
agreement on abandoned fishponds and
obtaining the rights for coastal communities
to manage the resources.
b. Establishment of greenbelt sites for
mangrove by planting mangrove seedlings in
the mangrove swamps.
c. Establishment of eco-tourism sites to help
restore mangrove forests and generate
income in the community

32. Do this! Read and study
on Government protected
sanctuary and on
Government protected
wildlife sanctuary to
answer activity 1.3 and
activity 1.4

34. Ways of
Protecting and
Conserving
Wildlife

35. 1.Protect a sanctuary
A sanctuary is a place
declared by the
government as a
protected area, such as:

37. a. Calauit Game Reserve and Sanctuary in Palawan

38. Ursula Island

41. 2. Support projects of the
government in protecting
the wildlife ecosystem,
such as:

42. a. The Phil. Eagle Conservation Project (Makiling Botanical Garden)

45. The Tamaraw Conservation Project (San Jose Occidental, Mindoro)

46. 3. Visit captive breeding areas
Captive breeding saves endangered species.
Captive breeding is done in the zoo or on
specialized clinics.
4. Do not buy products made from animal
parts.
5. Join organization that conduct educational
campaigns and give information on how to
protect and conserve the wildlife
conservation.
6. Help raise funds to support projects for
wildlife conservation.

49. A- Activity 1.5
Directions: Read and understand the
description of species on the table as
to status (EW) Extinct in the Wild,
(EN) Endangered or (VU) Vulnerable;
Range and Reason for decline to
answer the crossword puzzle. Write
your answer on the attached activity
sheet no. 5

51. Extinct in the Wild (EW): Species only
survives in cultivation, captivity, or
as a naturalized population well
outside of its native range.
Endangered (EN): Species faces very
high risk of extinction in the wild in
the near future.
Vulnerable (VU): Species faces high
risk of extinction in the wild in the
medium-term future.
