3. Ecology
Ecology is……
The study of interactions between living (biotic) and non-living (abiotic) components in ecosystems.

4. Ecosystems
An ecosystem is a complex, self regulating system in which living things interact with each other and with non-living things.
Ecosystems come in all sizes and are made up of different biotic and abiotic factors.

7. Using the following diagram, list as many abiotic and biotic factors that you can!

8. Using the following diagram, list as many abiotic and biotic factors that you can!

9. Sustainability
Sustainable: populations of plants, animals and other living organisms can continue to interact and reproduce indefinitely.

10. Parts of an Ecosystem
Species: group of organisms in an ecosystem that can reproduce with each other, and their offspring are viable
Population: groups of members of the same spp. that live in the same area
Community: populations of different spp. (biotic factors) that live and interact in an area
Niche: organisms role in an ecosystem

11. Ecosystems combine to make biomes!
large geographical area that contains similar ecosystems
categorized by plants, temperature and average rainfall
There are 5 terrestrial (land) biomes in Canada, and 2 aquatic (water) biomes.
Biomes combine to make the biosphere!

12. Biosphere
 The part of the planet, including water, land and air, where life exists.

13. There are 3 main components that make up the physical environment of the biosphere:
Atmosphere
Lithosphere
Hydrosphere

14. The Atmosphere Layers of gases that surround the Earth
Contains water, carbon dioxide, ozone
Helps keep the planet warm

15. The Lithosphere Earth’s solid, outer layer
Includes the rigid crust and upper mantle
Runs 100km down from the surface
Includes soil

16. The Hydrosphere All the water on Earth
~97% of this water is salt water in the Earth’s oceans
All living things depend on water for survival

17. Can these spheres work on their own?
