2. Learning Goals and Success Criteria
I will learn about the connections within an ecosystem.
I can distinguish between biotic and abiotic parts of terrestrial and aquatic ecosystems.

3. Ecology is …
The study of living things and how they interact with each other.

4. What do you see?
A trip to the moon gave astronauts a very special view of Earth, a view of an Earth where everything is connected.

5. Life is Everywhere Living things are found almost everywhere on Earth!
Each living thing makes its home somewhere.
Many organisms even make your body their home.
What different ecosystems can you identify in the picture on the left?

6. Ecosystems are Everywhere
Living things make their homes in the places they do because these places provide them with what they need to survive.
What different ecosystems can you identify in the picture on the left?

7. Ecosystems are Everywhere
Ecologists study how living things interact with each other and with their environment.

8. Ecosystems
Any group of living and non-living things interacting with each other.
The size of an ecosystem can vary.

9. Parts of an Ecosystem
All living (or previously living) things in an ecosystem are the biotic parts of the ecosystem. They include micro-organisms, plants, and animals.

10. Parts of an Ecosystem
The non-living parts of an ecosystem are described as being abiotic. Examples of abiotic things include the soil, the water, sunlight, temperature, and air in an ecosystem.

11. Parts of an Ecosystem
To function and stay healthy, the biotic parts of an ecosystem interact with each other as well as with the abiotic parts.
An ecosystem is a system that is made up of all the interacting biotic and abiotic parts of a certain place.

12. Terrestrial and Aquatic
A terrestrial ecosystem is an ecosystem that is based mostly or totally on land.
An aquatic ecosystem is an ecosystem that is mostly or totally in water.

13. Terrestrial and Aquatic
A habitat is a place where a population lives.

14. Biological Levels of Organization
An organism represents an individual living thing.

15. Biological Levels of Organization
A population is a group of organisms of the same type living in the same place at the same time.

16. Biological Levels of Organization
A community represents different populations living and interacting together.

17. Biological Levels of Organization
An ecosystem is formed when a community interacts with abiotic components (soil, water, space).
