Earth is a system
![Page 2: Earth is a system. The Biosphere The narrow layer of Earth where life can exist. Life on Earth requires: A. Liquid water B. Temperatures between 10°C.](https://reader035.fdocuments.us/reader035/viewer/2022062407/56649e4d5503460f94b43bbf/html5/thumbnails/2.jpg)
The Biosphere
• The narrow layer of Earth where life can exist.
Life on Earth requires: A. Liquid water B. Temperatures between 10°C and 40°C
C. Source of energy 1. Plants &
algae use sunlight to make food
2. Most other organisms get energy from what they eat

Ecosystems: Everything is
Connected

What is an ecosystem?
• An ecosystem is all of the organisms living in an area together with their physical environment.– Ex: Forest, coral reef,
your backyard• The components of an
ecosystem are constantly interacting with each other
![Page 5: Earth is a system. The Biosphere The narrow layer of Earth where life can exist. Life on Earth requires: A. Liquid water B. Temperatures between 10°C.](https://reader035.fdocuments.us/reader035/viewer/2022062407/56649e4d5503460f94b43bbf/html5/thumbnails/5.jpg)
Think – Pair - Share
1) What are the components of the ecosystem pictured?
2) Identify possible interactions between organisms in this ecosystem.
![Page 6: Earth is a system. The Biosphere The narrow layer of Earth where life can exist. Life on Earth requires: A. Liquid water B. Temperatures between 10°C.](https://reader035.fdocuments.us/reader035/viewer/2022062407/56649e4d5503460f94b43bbf/html5/thumbnails/6.jpg)
Components of an Ecosystem
• All ecosystems need basic components in order to survive.1) Biotic Factors – living and once living parts of the ecosystem– Ex: plants, animals, leaves, organisms’ waste
2) Abiotic Factors – nonliving parts of the ecosystem– Ex: air, water, rocks, sunlight
Which parts of the coral reef are biotic? Which are abiotic?

INQUIRING MINDS WANT TO KNOW…
Think back to your stick figure…
- Are we all part of the same ecosystem?
- Is someone in China part of our ecosystem?

What’s in an Ecosystem?Organism – an individual living thing Ex: a fish
Population –members of the same species that live in the same area at the
same time Ex: all catfish in a pond
Community – different species living in the same place and interacting with each other. Ex: insects, fish, frogs, & plants in a pond.
Species - a group of organisms that can mate to produce fertile
offspring Ex: Catfish
Habitat - the place where the community lives. Ex: the pond the catfish live in.

Think about it…• Can an organism live outside of its
habitat for a long period of time? Why/why not?

Stop… T-P-S Time
1) Classify the following pictures on your own using the terms:
organism, population, community, or habitat.
2) Pair up with your partner to compare your results.

Levels of complexity of living organisms on Earth
![Page 17: Earth is a system. The Biosphere The narrow layer of Earth where life can exist. Life on Earth requires: A. Liquid water B. Temperatures between 10°C.](https://reader035.fdocuments.us/reader035/viewer/2022062407/56649e4d5503460f94b43bbf/html5/thumbnails/17.jpg)
Everything is Connected• You can think of an ecosystem as
working like a car. The engine of a car is made up of hundreds of parts that all work together.
**Think about it - What might happen to the car if one of these parts breaks?
![Page 18: Earth is a system. The Biosphere The narrow layer of Earth where life can exist. Life on Earth requires: A. Liquid water B. Temperatures between 10°C.](https://reader035.fdocuments.us/reader035/viewer/2022062407/56649e4d5503460f94b43bbf/html5/thumbnails/18.jpg)
Everything is Connected• The same applies to an
ecosystem.• So, what might happen to an
ecosystem if one part is changed or destroyed?
• Simpson’s clip

Model Ecosystem • Create a model or blueprint for your given
ecosystem.
• The blueprint should include the following and be labeled with: – Habitat/location– Biotic factors in the ecosystem (at least 3)– Abiotic factors in the ecosystem (at least 3) – The interactions among the ecosystem’s community and
habitat (at least 1 per member of the ecosystem)– A population– A community– A description of how the ecosystem may be threatened by
human activities (how might the ecosystem be negatively impacted by human actions?).
