Food Chain

Food Chains & Organisms Lesson & Quiz

Materials & Directions

• You need your Science Journal, a pencil, and colored pencils.

• You will write each definition on the same page as your Food Chain notes.

• You will then draw and label an example of a food chain.

• You will attach a picture of your notes to this assignment on Google Classroom.

REVIEW

The next 2 slides review concepts that you wrote in your Science Journal on Monday.

Review:

• food chain: a diagram of living things that shows what an organism eats and is eaten by

• predator: animals that hunt or eat other animals

• prey: animals that are hunted or eaten by other animals

Review:

• All food chains start with the sun ☀️

• The sun is the main source of energy.

• The arrows in a food chain show the flow of energy.

Key Vocabulary & Diagrams

The next several slides include new vocabulary and a food chain diagram that you need to add on to the notes that you have already started.

Key Vocabulary

• producer: a living thing that takes energy from the sun and makes (produces) its own food (usually a plant)

• consumer: a living thing that needs to eat (consume) food to get energy (animals and humans)

• decomposer: an organism that breaks down other dead and dying organisms

Types of Consumers

• herbivore: consumers whose primary food source is producers (plant eaters)

• carnivore: consumers whose primary food source is other consumers (meat eaters)

• omnivore: consumers that eat both producers and other consumers

Food Chain Example

Draw and label each part of the food chain example in your journal (hint-keep your drawings SIMPLE)
