14. Biodiversity
There are over 1.7 million classified species
known to scientists.
It is estimated that there are about 15 million.
15. What is a species?
Biological Species: all
members of a population
that can breed under
natural conditions and
produce fertile offspring.
(With some exceptions:
there are some animals of
different species that can
have fertile offspring)
16. What is a Example of
Hybridization:
species?
Orange + Pomello
However, hybridization
and asexual reproduction
make this definition
tenuous.
= Grapefruit
21. Biodiversity
The physical conditions within an ecosystem must
also be varied to house these different species. This
is called structural diversity.
26. Biodiversity
3 - Transportation
Ex. Burdocks have
small hooked spines
on their heads that
stick to the fur of
animals that pass
by. This is used for
seed dispersal.
27. Biodiversity
4 - Reproduction
Ex. Bees transfer
pollen between
flowers to help the
flowers perform
sexual reproduction.
28. Biodiversity
5 - Hygiene
Ex. The Egyptian
plover gets it diet by
eating food scraps in
the teeth of
crocodiles.
