4. LET’S
RECALL

5. What is Biodiversity?

11. 3 Levels of
Biodiversity

12. 1. Species Biodiversity
 It describes the
variety in the number
and abundance of the
species within a
region.
 For example,
monkeys, dragonflies,
and meadow beauties
are all different
species.

13. 2. Genetic Biodiversity
 The amount of
variation in genetic
material (DNA) within
a species or within a
population.
 Chihuahuas, beagles, and
Rottweilers are all the
same species —but
they're not the same
because there is variety
in their genes.

14. 3. Ecosystem Biodiversity
 It describes the
assemblage and
Interaction of species
living together and
the physical
environment of a
given area.

29. Many human activities disturb the
balance in the ecosystem. All of these result
in ecological imbalance. Ecological
imbalance happens when there is a
disturbance which is either natural or man-
made disturbance that disrupts the balance
of an ecosystem.

30.  the addition of contaminants
or harmful substances into a
natural environment.These
contaminants are considered
pollutants and can damage
the quality of the air we
breathe and the water we
drink.
 2 major types- air pollution
- water pollution
1. POLLUTION

31.  Air pollution happens when solid, liquid, and
gas particles are dispersed into the air. Both
man-made and natural activities contribute to
air pollution.
• burning of fossil fuels
• exhaust from the vehicles and factories
• burning of plastics
• wildfires and volcanic ashes
1. POLLUTION

32.  respiratory
diseases
 acid rain
 global
warming
What are the effects of air pollution?

33.  Water pollution occurs when harmful
substances—often chemicals or
microorganisms—contaminate a stream, river,
lake, ocean, aquifer, or other body of water,
degrading water quality and rendering it toxic
to humans or the environment.
• improper waste disposal
• illegal fishing
1. POLLUTION

34.  fish kill
 water-borne
diseases
(amoebiasis)
 eutrophication
What are the effects of water pollution?

35.  happens
when forests
are cleared to
make the land
available for
other
purposes.
 Kaingin
system
2. DEFORESTATION

36.  drought
 floods/
landslides
 animal
extinction
 wildfire
What are the effects of deforestation?

37.  Overharvesting or
overfishing
 Dynamite fishing
 Cyanide fishing
 Muro-ami fishing
 Conversion of coastal
areas to resorts
3. DESTRUCTION OF COASTAL RESOURCES

38.  coral reef
destruction
 death of marine
animals
 scarcity of food
 water pollution
What are the effects of destruction the
coastal resources?

39.  Poaching is
the illegal
hunting,
capturing,
and often
killing of
wild animals.
4. ANIMAL POACHING

40.  animal
extinction
 spread of food-
borne illnesses
What are the effects of animal poaching?
