• Pen & highlighter

Topic 2 Lesson 2

Plan for today

• Class rules
• Explanation T2.1 Foodchains
• Make exercises in your textbook 
• Make 'food web simulation' exercises 

Class rules

1. When the teacher is speaking, be quiet
2. When someone is asking or answering a question, be quiet and listen
3. Work according to the traffic light color:                                                                        Red = quiet                        Orange = whispering                   Green = speaking
4. Do not touch other people(’s stuff) without permission
5. You treat each other with respect                                                                                                     

• If you do not follow the rules: max 1 warning --> 2.01

Learning goals

• I understand and can read food chains
• I can distinguish the different roles in a food chain (producer, primary consumer, secondary consumer, tertiary consumer and quaternary consumer)
• I understand the energy pyramid and understand why energy gets lost

Key words

• Organism
• Photosynthesis
• Joule (or calorie)
• Foodchain
• Energy flow
• Producers
• Primary consumer
• Secondary consumer
• Tertiary consumer
• Foodweb
• Sustainable

Food chain

A food chain shows you who eats 

whom in an easy way.

The energy flow is a way to show 

where energy is transferred.

It is shown with arrows.

Food chain

Producers are plants, because they 

produce food with photosynthesis

Consumers are animals that eat other 

organisms.

We use the words primary, secondary and 

tertiary to describe if they are the first, 

second or third consumer in the chain

Food webs

A food web shows all feeding 

relationships in an area.

Food chains and food webs

Food web

Energy pyramid

The energy pyramid shows that you 

lose energy with every step in the food chain. 

This is because:

Consumers don’t eat the entire organism

Organisms use up some of the energy 

Organisms produce waste that has some energy. 

PRODUCERS

CONSUMER

FOODWEB

FOODCHAIN

Shows one possible path of energy flow

Organism that feeds on other organisms

Shows all feeding relationships in an area

Organism that uses photosynthesis

What is on top of the food chain?

1. Producer
2. Consumer
3. Decomposer
4. Scavanger

Read the book

Go to page 46 and 47 in your textbook

Read the pages alone in silence

Done? Start making the exercises of T2.1 (E1 - 11  P48-53)

Assignment 'food web simulation'

You can find the assignment 'food web simulation' in classroom

Follow the instructions

Make sure you hand it in before the next lesson

Homework
