Ecosystems: Lesson 1, Activity 2
Your ideas about “Where is the Carbon in
Ecosystems?”

What is an ecosystem?
An ecosystem is a place that has the same climate, landforms, soils and vegetation.

Where is the meadow
ecosystem?
![Page 4: Ecosystems: Lesson 1, Activity 2](https://reader035.vdocuments.net/reader035/viewer/2022062218/56815ee6550346895dcd8ba1/html5/thumbnails/4.jpg)
Meadow ecosystem is outlined in
red.
The rest of the image is a
forest ecosystem.

Meadow ecosystems have many living things:
• Plants: • Animals:

Name all the places where you would find carbon in an ecosystem:1.
Where is the carbon in the ecosystem?
![Page 8: Ecosystems: Lesson 1, Activity 2](https://reader035.vdocuments.net/reader035/viewer/2022062218/56815ee6550346895dcd8ba1/html5/thumbnails/8.jpg)
For all of the places you named, what kinds of molecules are the carbon atoms in?
Which of those molecules are organic versus inorganic?
Where is the carbon in the ecosystem?

Where are the producers?
Producers do photosynthesis to create organic materials for food and for the materials that make up their parts

Where are the herbivores?
Herbivores eat plants and digest plant materials for food and for the organic materials that make up their parts

Where is the carnivore?
Carnivores eat other animals and digest animal materials for food and for the organic materials that make up their parts

Where are the decomposers?
Decomposers eat dead stuff and digest dead materials for food and for the organic materials that make up their parts

Scientists group parts of ecosystems into “pools” of carbon

What is soil organic carbon?
It is a pool of carbon that contains: • dead plants and animals waiting to decay (be
eaten by decomposers) AND• the organic material of live decomposers.
