1. BIODIVERSITY

2. BIO living organisms
diversity different kinds

3. Biodiversity refers to the
variety of living species on
Earth, including plants,
animals, bacteria and fungi.

4. Biodiversity different
kinds (types) of
organisms in one place

6. Species
a group of organisms that can
reproduce with one another in
nature and produce fertile offspring

7. Why is
biodiversity
important?

8. Importance of
Biodiversity
since a healthy ecosystem
relies on different kinds of
species to work together,
presence of different kinds of
organisms makes the
ecosystem balanced.

9. How de we
know if an
ecosystem have
biodiversity?

10. Biodiversity is
measured
through
POPULATION
DENSITY

11. What is
population
density?

12. POPULATION
DENSITY refers
to the number of
organisms in a
specific area

14. Types of Population Density
• High Index Diversity
• Low Index Diversity

15. Index of Diversity
Measures how many different
types of species (organisms)live
in a community

16. What affects
biodiversity?

17. Biodiversity is affected by
its Carrying Capacity and
Limiting Factors

19. How will you
describe the
state of fish in
the bowls?

20. Carrying Capacity is the
maximum size of the
population an environment
can support

21. Farmers must be careful to not let cattle
overgraze. Once an area is overgrazed it can
take a long time for nutrients to return to the
soil, and for grasses to regrow. In the
meantime, the area has reached its carrying
capacity as it can no longer sustain any new
cattle. Perhaps the carrying capacity has even
been surpassed if the area cannot fully
support some of the existing cattle.

23. Limiting factors is anything that
constrains/limits the a population’s size
and slows or stops it from growing. Some
examples of limiting factors are foods,
mates, and competition with organisms for
resources.

24. If there are not enough prey animals
in a forest to feed a large population
of predators, then food becomes a
limiting factor. Likewise, if there is
not enough space in a pond for a
large number of fish, then space
becomes a limiting factor.
