Flow of Energy Through an Ecosystem (Food chains and Food webs)

Producers, Consumers and Decomposers

Food Chains and Food Webs. A food chain shows how each living thing gets its food. Plants are called producers because they are able to use light energy.

The main source of energy for life on Earth comes from the Sun. Plants use light energy from the sun to make food.

18.2. All living things need energy to survive Everything we do requires energy Organisms are divided into three groups based on how they get their energy.

Food Web Producers, consumers, & decomposers. Three main components to the food web Producers Consumers Decomposers.

Ecosystem Components Producers – Basis of an ecosystem’s energy – Autotrophs: perform photosynthesis to make sugars – Chemotrophs: Bacteria which use.

Pp Learning Goals By the end of this lesson, you should: Know the difference between a producer (autotroph) and a consumer (heterotroph) Know.

3 Note Cards 1. Decomposer (Detritivore) 2. Producer 3. Consumer * Word and picture on the front/ definition on the back

- Use the following desert organisms to draw a food web - Use the following desert organisms to draw a food web. - Draw the arrows in the direction of nutrient/energy flow - Label the decomposers, producers and consumers. Coyote Stink bug Burrowing owl Grasshopper Mouse Desert Desert Indigo Bush Dandelion Cottontail Earthworm

Answer the following questions on the bottom of your food web. What would happen to the other organisms if the coyote went extinct? What would happen if there was a long term drought and all of the producers disappeared ? What would happen if all of the decomposers disappeared?

Construct a Food Web Use the following information to construct a food web in a meadow ecosystem: Red foxes feed on raccoons, crayfishes, grasshoppers, red clover, and gray squirrels Red clover is eaten by grasshoppers, muskrats, and red foxes Grey squirrels and raccoons eat parts of white oak trees Crayfishes feed on green algae and detritus(disintegrated organic material) and they are eaten by muskrats and grey foxes Raccoons fed on muskrats, grey squirrels, and white oak trees. Identify herbivores, carnivores, omnivores, and detritivores. Describe how the muskrat would be affected if disease kills the white oak tree.
