1. Introducing Ecosystems
organism: an individual living thing (a single form for life)

2. Introducing Ecosystems
species: individuals who can breed together to make fertile offspring

3. Introducing Ecosystems
species: individuals who can breed together to make fertile offspring
e.g. rabbits are but horses and donkeys are not. This is because when horses and donkeys breed, they create mules, which are not fertile meaning that mules cannot produce offspring.

4. Introducing Ecosystems
species: individuals who can breed together to make fertile offspring
population: all the members of the same species that live in the same ecosystem

5. Introducing Ecosystems
species: individuals who can breed together to make fertile offspring
population: all the members of the same species that live in the same ecosystem e.g. a deer population

6. Introducing Ecosystems
species: individuals who can breed together to make fertile offspring
population: all the members of the same species that live in the same ecosystem
community: all the living organisms, from all the populations, that live in the same ecosystem
e.g. Beaver Pond community

7. Introducing Ecosystems
e.g. Beaver Pond community members
List all the
Living things you see!!

the features, such as nests, associated with
their activities

of an ecosystem

36. Earth System
(Parts of Our Planet)

37. Earth System
Biosphere: the zone in, on, and around Earth where life can exist.
-made up of four parts:

38. Earth System
1) Lithosphere: the rocky outer shell of Earth. -consists of mountains, ocean floors, and the
rest of Earth's solid landscape

39. Earth System
2) Hydrosphere: the water on, above, or below
Earth's surface
-consists of oceans, lakes, rivers, ice, clouds,
and groundwater

40. Earth System
3) Atmosphere: the thin layer of gases that
surrounds the planet
-contains gases such as water vapour,
oxygen, and carbon dioxide
-acts like a blanket wrapped around the
Earth and prevents Earth from getting too
warm or too cool

41. Earth System
4) Ecosphere: the parts of the biosphere where
life actually occurs
