9. BIODIVERSITY
May be defined as the totality of different organisms, the
genes they contain, and the ecosystems they form.
Is the diversity within and among species and ecosystems.
Refers to the number of biological species that exist in a
given region.
When an ecosystem has a high number of species present it
means that it has a high biodiversity.
BIODIVERSITY 06/17/2021 9

10. BIODIVERSITY
The high number of species ensures the stability of an
ecosystem because it has a better chance of coping with
environmental stressors such as floods, droughts, and
diseases.
The variety of species means that when there is a decrease
in the population of one species, other species can
compensate for their loss, thus minimizing the effects on the
environment.
BIODIVERSITY 06/17/2021 10

11. HIGH BIODIVERSITY
Means that a region supports a wide
variety of species, while low biodiversity
implies that an area supports only a
few.
Reasons for variances in biodiversity
are complex, but they include both
natural and man-made causes.
The flow of energy is the most
important factor that controls what kinds
of organisms live in an ecosystem.

13. FOOD CHAIN
Shows the sequence of how energy is transferred from one
organism to another.

14. TROPHIC LEVEL
Organisms’ feeding position in a
food chain.
A step in nutritive series of an
ecosystem.
Organisms at each level are
classified into based on their
feeding behavior.
The amount of energy at each
trophic level decreases as it moves
through an ecosystem.
