CH. 14 Sct. 1 Food Webs

LT: I will describe how Food Webs influence animal development.

I.                    Trophic Levels

1. Autotrophic – makes its own food using energy from the sun
2. Heterotrophic – eats other organisms to get energy

II.                  Food Web Roles

1. Producer – autotrophic

1.)    Plants, algae

2. Consumer – heterotrophic, feed on living things

1.)    Includes plant eaters and meat eaters

Tertiary Consumers (Carnivores)

Secondary Consumers (Omnivores)

Primary Consumers (Herbivores)

Primary Producers (Producers)

3. Decomposers – heterotrophic, break down wastes and dead organisms into simple compounds

1.)    Fungi and Bacteria

III.                Energy Availability

1. Only some of the energy in an organism moves up the food web when its eaten
2. Energy in a food web is lost as organisms use it to move, grow, reproduce
3. Producers have the most energy available

1.)    As you move up the food chain, less and less energy is available

L.T.: I can explain the role photosynthesis plays in a food web.

                                            

              Today in class we talked about photosynthesis. We created a drawing of the textbook simulation, see previous post.
