environments.

Species –
That’s right!!! If you can’t make a
baby with it, it’s not from the same
species.
Ex: The elephant cannot make babies
with the eagle… therefore they are not
from the same species.
"Biological diversity refers to the
variety of species and ecosystems
on the Earth and the ecological
processes of they are a part of."
The main components of
biodiversity are:
1. Diversity Between Ecosystems:
the different types of living
communities and the
environments, such as marshes,
lakes, streams and forests, in
which they are found
Ecosystem –
Living = biotic (
Non-living = abiotic (
)
)
2. Diversity Within Ecosystems :
- occurs within
(members of a species
that live in a specific area and share the same resources) of organisms living
within a particular ecosystem
Ex: Diversity within all living organisms in the Canadian Rockies
3. Diversity Within Species:
Occurs within
organisms of the
.
Ex: Diversity within all humans.
4. Genetic Diversity :
occurs within organisms at a
variety of genetic material in all living things.
, as it describes the
5. Species Distribution:

Plant and animal species are not distributed evenly throughout
the various eco-regions of the world.

Most of the different species of plants and animals can be found
in tropical regions and, more specifically, in the rainforests.

As you move closer to the poles of the Earth, there is less
biological diversity
