Food Chains

Food Chains

TEKS Objective

Gather evidence of interdependence among living organisms such as energy transfer through food chains and animals using plants for shelter.


Essential Understanding

The student knows that the living environment is composed of relationships between organisms and the life cycles that occur.

Science Background

Food Chains and Cycles: BBC Bitesize (website) - Food chains illustrate the feeding relationship between living things. Learn more about the transfer of energy through food chains as you navigate this website.

Another Link in the Food Chain: Geography4Kids (website) - Quick review of the major components of food chains, along with an explanation of producers, consumers and decomposers, and their interactions.

Food Chains and Food Webs: Virtual Teacher Aide (website) - Our bodies use energy every time we move or exercise or walk in the park. Where do we get the energy to do these things? Read this article about food chains and food webs helps to answer this question, and more.

Signature Lesson

Food Chains: Illinois Institute of Technology (website) - Students role play and use peanuts as energy sources, as they model a simple food chain involving plants, mice, snakes and hawks.

Supporting Lessons

Cycle of Life - Food Chain: Science Netlinks (website) - Students share their ideas and watch a short video clip about food chains, before completing an online interactive game on the same topic.

Elaboration Lessons and Extensions

Investigating Local Ecosystems: Science NetLinks (website) - Students investigate the habitats of local plants and animals and explore some of the ways animals depend on plants and each other.

The Antarctic Food Chain: National Geographic (website) – Students learn about animals of Antarctica and create a wall collage that shows how energy is transferred within food webs in that environment.

Assessment Ideas

Give students a few photos or illustrations of organisms at the bottom of a food chain, and have them draw pictures of the predators that consume those organisms.
