2. LESSON OUTLINE
Importance of Ecosystems
Major Ecosystem and Resources
Population Growth and Sustainable Development
3. IMPORTANCE OF ECOSYSTEM
Provide and store clean fresh air
Maintain air quality
Regulate climate
Mitigate (lessen) floods and runoff
Prevent erosion
Maintain soil productivity
4. IMPORTANCE OF ECOSYSTEM
Store and recycle nutrients
Abate (decrease) noise
Pollinate crops
Maintain biological and genetic diversity
Provide recreational opportunities
Supply habitats
Provide medicines, food, fiber and energy
5. MAJOR ECOSYSTEMS IN THE
PHILIPPINES
Tropical rainforests
Grasslands
Freshwater biomes
Coral Ecosystems
6. Tropical Rainforests
High humidity and high
temperature (25-35℃)
Large amount of rainfall (200 cm)
yearly
Thick, diverse canopies of plants
and trees
Diverse community of animals
(>3500 plants and animals)
7. Tropical Rainforests
Because a tropical rainforest is
abundant with plants, nutrients
present in the soil are quickly
absorbed.
Therefore, the soil here absorbs
little organic matter.
8. Tropical Rainforests
Most of the tropical
rainforests are found in:
Zambales
Palawan
Mountain Province
Mt. Makiling
Mt. Makiling
9. Grasslands
Abundant with grasses
Includes many species of
grasses and wildflowers
Vegetation is dense esp.
in areas near the river
Animals like rats, insects,
snakes and birds thrive
12. Freshwater Biomes: RIVER
Long body of water that
flows toward another
river, lake, or ocean
Ex. Pasig river, Marikina
River, Cagayan River,
Pampanga River
Cagayan River
13. Freshwater Biomes: LAKE
Large body of water
surrounded by land
Ex. Taal Lake, Laguna de
Bay, Lake Caliraya,
Naujan Lake, etc.)
Taal Lake
14. Freshwater Biomes: ESTUARIES
Junction of water where
water from rivers,
streams, and lakes meet
the ocean
Rich in fishes and
shellfishes
Ex. mangrove
15. Mangrove
Tall, evergreen forests
w/ roots that twist
upward and downward
Some thrive in more
saline area while others
in freshwater areas
Manjagao Mangrove
Forest, Surigao City
16. Marginal Forests
Extreme conditions exist
(temperature, salinity,
winds, solar radiation,
aridity, flooding, etc.)
Few organisms thrive or
live here because of
these extreme conditions
17. Coral Reefs
One of the most colorful
and beautiful natural
resources in the world
Diverse in marine
animals
Ex. Tubbataha Reef
Tubbataha Reef
18. Manmade Ecosystems
Built for human’s need
and care for those
organisms that need
habitats
Examples (fishponds,
botanical gardens,
wildlife sanctuaries,
farms, etc) Baguio Botanical Garden
19. Manmade Ecosystems
Wildlife sanctuaries are
built for the endangered
species of animals like our
very own Philippine eagle,
tarsiers, and tamaraws.
Ninoy Aquino Parks and
Wildlife Center, Quezon City
21. As population continues to
increase, these natural
ecosystems continue to be
destroyed by manmade
activities.
Philippines currently has a
population of 109,615,912,
the twelfth (12th) in the
world.
Slums in Manila
28. In the underdeveloped
countries, birth rate
remains very high.
Death rate has also been
lowered because of
improved conditions.
However, underdeveloped
countries experience
survival problems because
of lack of food, resulting in
large number of
malnutrition and hunger.
