This document discusses ecosystems and interactions within an ecosystem in Barangay Valenzuela. It describes the biotic and abiotic factors present, including plants, animals, soil, air and water. Specific nutrient cycles are mentioned, such as the carbon-oxygen cycle. However, the ecosystem is threatened by pollution from garbage and improper waste disposal. Improper waste disposal could block drainage and cause land pollution if not addressed.

 The study of the interrelationships
between organisms and their
environment.

6. The Different Interaction In our
Ecosystem

7. Biotic-Biotic
Interaction
 Relationships among biotic
factors in the community.
As we can see, the bee
depends it’s living on the flower
and they are both Biotic
Factors.

8. Biotic-Abiotic
Interaction
 Relationships between the
community and the physical
environment.
As we can see, a dog is resting
on its cage. This illustrates that the
dog is the biotic factor while the
cage is the abiotic factor.

• A peaceful barangay near
Barangay Cojuangco and
an another way to go to
Cabanatuan City.

11. Some of the interaction of the
living and non-living things is
by a store.

12. And one of the Nutrient
Cycle that do exist here is
the:

13.  Carbon-Oxygen Cycle
13
Respiration
Carbon Dioxide
Photosynthesis
Oxygen added to
air carbon dioxide
removed from air.
Oxygen
Oxygen removed from the air
carbon dioxide added to air .

14. But the ecosystem of the
said barangay is affected
by throwing garbage's
everywhere and on an
improper place 

21. And because of this mess, if
there is a storm coming, the
canals/drainages can be
blocked by the
plastics, etc. 
21

22. We also saw a junk shop or a repairing
station which is full of used oils and
other poisonous liquids.
22

23. And this mess can cause
LAND/SOIL POLLUTION that
can destroy the natural
nutrients that we can found
on the soil.
23

24. It do also have a warehouse of pig
pellets/food that can affect many
people by it’s smell.

25. So, let us now clean some
mess to prevent the revenge
of Mother Earth 
But, how?
25

26. • By cleaning our surroundings :D
26

27. • Segregating Non -
Biodegradable to
Biodegradable
27

28. • Planting some plants
outside our house.

29. And we’ve
discovered that this
Barangay have this
Material Recovery
Faculty.
