Explore how different factors can cause a break in a food chain and may affect an ecosystem with this 16-slide teaching presentation.

What Factors Can Affect a Food Chain?

There are many different factors that can affect a particular species in an ecosystem. A food chain may be impacted by hunting, pollution, overpopulation or deforestation. This presentation aims to help students understand how these factors affect animals and plants negatively and predict what might happen if part of the food chain is broken.

Through this presentation, students will show they can identify and describe the flow of energy in a food chain and predict how changes in a food chain affect the ecosystem.

Tips for Differentiation + Scaffolding 

A team of dedicated, experienced educators created this resource to support your science lessons.

Group Lesson 

Project the slides onto a screen and work through them as a class. Encourage students to respond to the questions in their workbooks or on a mini whiteboard.

 Turn & Talk 

Invite students to pair up with someone in the seat nearest to them for a five-minute Turn & Talk. Keep students engaged and on task by directing them to focus on a specific topic, or let them freely discuss the content. Use this Turn & Talk session to encourage students to make space for each other by actively listening, asking questions, and practicing empathy.
