1. Chaparral Food Chains and Food Webs

2. Location of Chaparral Biome
This is the Santa Ynez Mountains, a chaparral located in Southern California.
A chaparral biome is created when cool seawater meets a landmass with high average temperatures.

3. Location of Chaparral Biome
Found in a little bit of most of the continents
All the blue highlighted area on the map is Chaparral Biome

4. Chaparral Climate Often called the Mediterranean climate
Mild and moist, but not rainy
During the summer it is very hot and dry
The temperature is usually mild but it can range is between 30° and 100° F

5. California Chaparral Plants
The plants that are adapted to dry summers
The plants conserve water through small, waxy leaves and using water efficiently.
The Chaparral contains 2,036 of plants other than trees.

6. Dominant Chaparral Plants
Bitter Cherry
Toyon
Chamise
Manzanita

7. Chaparral Animals

8. Food Webs Identify the: 1. Producers 2. Primary Consumers
2. Primary Consumers
3. Secondary Consumers
4. Herbivores
5. Carnivores
6. Omnivores
7. What elements are missing from this food web?

9. Identify the Groups
With the colored pencils mark each group a different color. For example mark the energy sources with yellow, the producers with green, the herbivores with blue, the omnivores with orange, the carnivores with red, the scavengers with purple and the decomposers with brown.

10. Label and Sort the groups
Use scissors to cut the pictures apart.
Sort the pictures into groups according to energy sources
producers, herbivores (first order consumers), omnivores (first or second order consumers), carnivore (second or third order consumers), scavengers and decomposers.

11. Make Two Food Chains
Construct 2 food chains as they would occur in the chaparral. Paste or tape your pictures into the spaces provided. Use arrows to show that energy is passed from one organism to another. (Arrows go from the animal that is eaten to the animal doing the eating). Show teacher

12. Make a Food Web
Use the same pictures to form a food web by first arranging them on your desk.
Remember that a food web is several food chains linked together.
Construct a food web as it would occur in the chaparral.
Glue or tape your food web to the paper.
Use arrows to show that energy is passed from one living organism to another.

13. Add the Poison Look at your food web.
All the insects have been sprayed with an insecticide (bug spray) such as DDT or chlorodane, or have eaten an organism that has been sprayed with one of these compounds.

14. Bioaccumulation
If animals also eat the organism that has been sprayed, they take in the poison.
The animals may not die, but the poison builds up in the organs of its body.
Because larger animals eat more food that may be affected with the poison, more poison is naturally concentrated in the larger animal(s).

15. Show the Impact
Take a dark colored pencil or canyon and mark all of the organisms in the food web that might get some of the poison into their bodies from their food. Include 1X, 10X, 100X or 1000X to indicate bioaccumulation. Show teacher
Put your name and period on the food web and turn it in with your questions (written on a separate piece of paper).
