Food chains and webs show the flow of chemical energy through an ecosystem. From the sun to producers to primary consumers to secondary consumers to tertiary consumers, students learn about the transfer of chemical energy and how producers and consumers depend on each other to survive. They also learn scientists classifiy living things based on groupings of what they eat. > Download PDF

 

Activity 1: Chemical Collisions

Chemical energy passing through the food chain starts with the sun.

 

Activity 2: Productive Primary Producers

Producers use energy from the sun during photosynthesis.

 

Activity 3: Primary Producer Eaters

Consumers get energy by eating producers and other consumers.

 

Activity 4: Consuming Critters

Consumers eat different types of food to get energy.

 

Activity 5: Web of Life

Food chains and webs show the transfer of chemical energy in an ecosystem.

 

Activity 6: Tropical Trophic Pyramid

Energy flows from the sun to producers to consumers.
