The document discusses biodiversity and the causes and impacts of species extinction. It defines key terms like species diversity, genetic diversity, ecosystem diversity, habitat destruction, overhunting, invasive species, pollution, and more. It also discusses the importance of adaptation and how adaptive traits are acquired. The end includes a quiz to test understanding.

7. sum of all the different
species of animals,
plants, fungi, and
microbial organisms
living on Earth, and the
variety of habitats in
which they live.

8. • SPECIES DIVERSITY
• GENETIC DIVERSITY
• ECOSYSTEM DIVERSITY

9. SPECIES DIVERSITY
• Pertains to the total number of
species that exist within a
region.
• Different kinds of organisms,
relationships among species.

10. GENETIC DIVERSITY
• Pertains to the variation of
genes between distinct species.
• Different genes and
combinations of genes within
populations.

11. ECOSYSTEM DIVERSITY
• Pertains to the variations of
ecosystems.
• Different habitats and species
interactions.

12. • EXTINCTION OF SPECIES
• LOSS OF SPECIFIC HABITATS
• LOSS OF GENETIC VARIATIONS
WITHIN A SPECIES

13. EXTINCTION OF SPECIES
• Species extinction is
the number one cause
of biodiversity loss.
EXTINCTION
• The entire species PERMANENTLY
DISAPPEARS from the biosphere.

14. LOSS OF SPECIFIC HABITATS
• The process by which a
natural habitat becomes
incapable of supporting its
native species.
• It is the PLACE where
organisms live.
HABITATS

15. MIGRATION
• It refers to the
survival of a new
species into an
already occupied
area.
ECESIS
• It refers to how
well the new
species adjusts to
the area’s
ecosystem.
AGGREGATION
• It involves the
reproduction of
the species after
it has
familiarized itself
with its new
place of
residence.

16. LOSS OF GENETIC
VARIATIONS WITHIN A
SPECIES
• The process by which a
species cannot cope up with
the changing environment.

17. • HABITAT DESTRUCTION
• COMMERCIAL HUNTING/HARVESTING
and HUNTING FOR SPORTS
• INTRODUCTION OF ALIEN, EXOTIC, OR
NONNATIVE SPECIES
• POLLUTION CAUSE BY HUMAN ACITIVIES
• OTHER CAUSES LIKE SUPERSTITION

18. HABITAT DESTRUCTION
• This pertains to the conversion,
fragmentation, and
simplification of any potential
natural habitats.

19. COMMERCIAL HUNTING/HARVESTING
and HUNTING FOR SPORTS
• This happens due to various
socio-economic factors and
man’s insatiable greed for
profit and material things.

20. INTRODUCTION OF ALIEN, EXOTIC OR
NONNATIVE SPECIES
• This happens when new species
have no predators in their new
habitats, so they crowd out the
vulnerable native species and
monopolize available resources
in the area.

21. POLLUTION
• This is cause by the industrial,
agricultural, and waste-based
pollutants.

22. OTHER CAUSES LIKE
SUPERSTITION
• This is cause by being ignorant
and misconceived ideas that
the organisms are very
dangerous and can bring bad
luck.

34. DOMINO EFFECT or
RIFFLE EFFECT
• It is the loss of plant species
triggers the extinction of
animals.

35. KEYSTONE SPECIES
• This refers to one whose
presence and activities
strongly affect other species
in the community.

36. ADAPTATION IS THE KEY FACTORS FOR
SPECIES SURVIVAL
• This means adapting to be able to survive
the climatic conditions of the ecosystems,
predators and other species that compete
for the same food and space.
ADAPTATION
• Pertains to the ability of the organisms
to respond to changes in the
environment.

37. STRUCTURAL
ADAPTATION
• It involves changes in the
morphology of the
organisms.

43. PHYSIOLOGICAL
ADAPTATION
• It involves
processes
occurring
inside
organisms.

44. BEHAVIORAL ADAPTATION
• It is the way an
organisms acts.
Example: mantis
behavior when
seeking, capturing,
and manipulating
prey.

46. SOURCES OF ADAPTIVE
TRAITS
• Adaptive traits can be
acquired during sexual
reproduction.
• Traits are carried by the genes.

47. IMPORTANCE OF
BIODIVERSITY
• ECOSYSTEM SERVICES
• BIOLOGICAL RESOURCES
• SOCIAL BENEFITS
